Chocolate and Courgettes (Zucchini)

Courgettes are innocent enough looking when they first arrive

– but soon they expand and take over your life like triffids. Beware the courgette.

Little did I know when I took delivery of my spiffing Rocket Garden of baby veg plants in April that it would be the courgettes that were the real trouble makers. They were so innocent, with just one or two oval leaves – looking no larger than any of the other plants, and much smaller than the strawberries, for instance. The directions recommended a distance of 45cm between plantings, which is more or less what they now have, but they now seem so large that they tower over the long since bolted lettuces and shriveled brown pea plants.

Courgette gluts are a gardening cliché, but with good reason – once they start producing, they don’t stop, and if you leave them for more than two days without checking, you will turn around to find a marrow has appeared.

So far the production has been a pleasant trickle – two or three courgettes every 4 or 5 days is very manageable, and can easily be converted into pasta – linguine, lemon juice, parmesan, oiive oil – or substitute for aubergine in a parmigiana.

However, we are now well into production on all four of my plants, so it’s more like 4 courgettes every other day. Serious help is clearly needed.

Courgettes

So when my mother-in-law asked me yesterday if I had any good courgette cake recipes, it occured to me that in fact I had the perfect one, but hadn’t tried it yet. I am referring, of course, to Chocolate and Zucchini cake from Clotilde’s Chocolate and Zucchini book (and from the blog of the same name).

Having once made a Jamie Oliver beetroot cake that was a disaster, I am wary of baked goods with vegetables in, but I have complete faith in Clotilde and I knew she would not lead me astray. And so it proved: as she notes in the book, if you didn’t tell anyone this had courgettes in, they would never tell. It’s just a really soft, moist chocolate cake, not too sweet. In fact, it could probably bear icing with something like buttercream and still be good. Even the olive oil I used in place of butter (as she suggests) is all but undetectable. So if you have courgette problems this summer, simply make endless batches of this and freeze where necessary.

Chocolate and Zucchini cake

Adapted, just barely, from Clotilde Dusoulier’s ‘Chocolate & Zucchini’

Ingredients

  • 240g plain flour
  • 60g cocoa
  • 1 teaspoon bicarbonate of soda (baking soda)
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon sea salt
  • 180g light brown sugar
  • 120ml extra virgin olive oil
  • 3 large eggs
  • 1 tsp vanilla extract
  • 1 tsp instant coffee granules or instant espresso powder
  • 350g courgettes (zucchini), grated – about 2 medium courgettes
  • 150g chocolate chips or chunks

Method

Preheat oven to 180°C/160°C fan/350°F.

Put the flour, cocoa, baking powder, bicarbonate of soda and salt into a bowl and use a whisk to mix everything together thoroughly and distribute the baking powder and bicarbonate.

Flour and cocoa mixture

Put the olive oil and sugar into a mixer bowl or food processor and combine for 3 or 4 minutes until thoroughly mixed together. It won’t cream as butter and sugar would, and may form clumps – don’t worry. Add the eggs one at a time, and mix thoroughly after each one, until the mixture is smooth again.

Oil, sugar, eggs, vanilla mixed together

Add the vanilla and coffee granules or powder to the egg mixture.

Meanwhile grate the courgettes fairly finely – I used the grating disc on my food processor, but it wouldn’t take too long with a hand grater.

Grated courgette

Add just over half of the flour mixture to the eggs and very gently mix until the flour hasn’t quite disappeared.

Toss the remaining flour with the grated courgettes and chocolate chips to coat them.

Mixing in courgettes and chocolate chips

Add this on top of the rest of the batter, and fold together gently with a large spoon or spatula.

Pour into a greased or lined tin.

Chocolate and courgette cake, ready to bake

I used a 2lb (large) loaf tin and 6 muffin cases. Clotilde recommended a 25cm springform tin. You could also do them all as cupcakes, which I’m guessing would make around 18.

Bake at 180°C (160°C fan)/350°F for about 20 minutes for the cupcakes, and 45 minutes for the loaf cake.

Remove from the oven and leave to cool for 10 minutes before removing from the tin. If you use a springform tin, unclip the outside at 10 minutes, but leave in the tin to cool completely.

The cupcakes are especially good when they’re still a little warm.

Learning (more) about chocolate

I’ve been on an uncharacteristic splurge in the last couple of weeks, and been to two different chocolate evenings. Although I consider myself a keen chocolate consumer, some would even say a chocolate snob, I surprised myself by how much I learnt on these two evenings.

The first was a demonstration session at Divertimenti, given by Paul A Young. I know him only by reputation, and because I got his beautiful book, Adventures with Chocolate, for Christmas. I haven’t even been to his shop, although it’s now on the list. This was a great evening – Paul’s passion for chocolate came through vividly, and was completely infectious. He started with a short run-down of how chocolate is made, and a tasting session that started with roasted nibs, and went through to several types of chocolate. Then he started the recipes, and elaborated on a few topics that he’s really keen on – using herbs with chocolate, and pairing chocolate with unusual ingredients, in this case a white chocolate sauce with sole. He spoke about flavour matching a lot – choosing which chocolate goes with what, whether it will overpower, what else to match with it to balance the flavours. The fish with chocolate was actually really good – not unlike fish with vanilla, if you’ve ever had that combination. Shallots, creme fraiche and aniseed notes from dill and Pernod balanced out the sweetness of the chocolate really well.

Inspired by this evening, I started browsing around seventypercent.com and came across their Chocolate Tasting Workshop. This was at the Scotch Whisky Society (who knew that existed?) and was really a series of tools to equip you for tasting chocolate. We looked at the way chocolate’s flavour changes over time, the many different notes you can distinguish, particular qualities that make chocolate ‘good’ or ‘bad’ – things like over roasting, a coarse texture, lack of length (the persistant chocolate aftertaste in the mouth), or a bad aftertaste. It covered quite a few things I knew, but also some new things. Most of all, it was good to put aside some time just to sit down and contemplate nothing more than the flavour and smell and texture of the chocolate you’re tasting. It might have been good to taste a wider range of chocolates, including some rubbish ones, but I can see how your palate would start to get overwhelmed very quickly.

Here are some things i’ve learnt from these two sessions:

  • I really like fruity chocolate – and I’m most likely to get that hit from Madagascan beans, hence my preferences for Valrhona Manjari and Malagasy Mora Mora.
  • I am pretty tolerant of all sorts of chocolate, equally happy to eat caramelly, biscuity (probably cheap ones) as the dark and bitter sort (although we’re still talking fine chocolate here: Galaxy is scum, and Dairy Milk is fine but gives me an unpleasant sugar-comedown).
  • Chocolate is ground down into very varied granule sizes, and some are much smoother than others. Brands like Amedei feel especially smooth and liquid. Green & Blacks is much coarser.
  • Water ganache is a revelation. I’d read about it before, but never made it, and tasting Paul A Young’s fresh mint ganache, made with just water, mint, sugar and chocolate has totally converted me. I’m now really keen to try this with tea – guinea pigs wanted!
  • The thing I most want to learn about next is tempering. I’ve done it a couple of times at home, but I would really love to be able to do it without having to clear the whole day – to make it something that I can contemplate doing in smaller quantities.

Some useful chocolate links that I’ve been collecting:

  • Seventypercent – a chocolate blog and (very comprehensive) review site for fine chocolate.
  • Paul A Young – lovely man, and great chocolates: the salted butter caramel I tried was indescribable, and has won 2 Gold medals. In Islington and the City.
  • Rococo – chocolate shops in Marylebone and Chelsea and also a chocolate school offering tempering and truffle-making classes.
  • William Curley – shops in Richmond and Belgravia.
  • Melt chocolates – little white boutique shop in Notting Hill and also available in Whole Foods
  • Matcha chocolates – recommended by Shuna aka eggbeater, so must be good 🙂

Birthday cake

Birthday cakes need to be so many things: celebratory; they need to fulfill the wishes of the birthday boy or girl rather than the baker; and demonstrate an appropriate level of effort. It’s this last one that can give me trouble. While I love to make a cake, and will use any excuse to do so, it sometimes feels odd to create something really elaborate for a work colleague or boss. And besides, I don’t often have the time to go overboard. This is where the chocolate torte comes in.

Chocolate torte is one name for a soft chocolate cake made with ground almonds. Other names are Reine de Saba, or Queen of Sheba cake, or it can simply be referred to as a flourless chocolate cake.

To give some idea of the amount of variation possible, I compiled this table from books I own (oh stop: you didn’t already know I was a geek?):

Author Nigella Lawson Sybil Kapoor Gordon Ramsay Alice Medrich Elizabeth David Julia Child

As with so many of my chocolate experiments, it began with Alice Medrich’s ‘Bittersweet’. She devotes a chapter to a number of variations on this recipe, and reassures the reader that this is a recipe that will accommodate, even welcome changes. She provides us with that elusive license to create almost infinite experimental variations, and still produce an edible result. There can be few experienced home cooks who don’t read through a recipe and mentally edit it. However, we are often admonished that one really ought to follow a recipe to the letter the first time, so you can understand the starting point. While that remains good advice, the freedom to add your own stamp right away is a great inducement to try this recipe. So here at last is a recipe that you can rearrange and make your own, and still produce something that everyone will be happy to eat – and provides a suitable celebration cake at the same time.

Chocolate torte:

Prepare a 20cm/8 inch springform or loose-bottomed tin, by lining the base with baking parchment.

150g dark chocolate (I used 64% Valrhona Manjari)
150g butter

–> melt together, and stir until smooth

1 cup espresso (I used about 1/2 tbsp instant espresso powder in enough water to just dissolve it)

2 tbsp brandy

–> mix into melted chocolate, and set aside

100g ground almonds

45g flour

–> measure and mix together

4 large eggs

–> separate into yolks and whites. If you have a stand mixer, use that bowl for the whites.

110g sugar

–> combine with the yolks and beat until well blended (you can do this by hand, or briefly with a machine)

–> stir in the melted chocolate to combine.

–> separately, whisk the egg whites to soft peaks

50g sugar

–> whisk in 50g sugar to make a meringue, and continue whisking until you have stiff peaks.

–> Fold the whites into the chocolate mixture, by first adding one-quarter, and thoroughly beating it in, then folding in the remainder.

–> Bake for around 30 minutes at 190C/375F, or until a skewer inserted about 4cm from the edge comes out clean, but one inserted in the centre is still gooey.

Chocolates

We have done a few classes in chocolate in recent weeks, and so I spent some time this weekend experimenting with some of the things we’ve tried.

Chocolate is very odd stuff. Good dark chocolate consists only of cocoa solids, cocoa butter, sugar and probably a little vanilla and lecithin (an emulsifier) to help it all stay together. It is particularly the cocoa butter which gives chocolate such unique properties. It is solid at room temperature, but melts quickly at around body temperature, giving it those melt-in-the-mouth properties.

The fats in cocoa butter tend to form large crystals, which can be of 4 different types. Only one of these types, the beta crystals, is a stable form. When you buy chocolate, it is tempered, meaning that the fat is mostly in beta crystals. This means that the chocolate is shiny, will snap when you break it, and will melt at a slightly higher temperature (95F/ 35C). Once you melt the chocolate, other crystal types will prevail, and the cocoa butter might separate from the cocoa, forming white blotches or streaks (you sometimes see this when you leave a chocolate bar in the sun and then cool it down again).

So the trick is to melt the chocolate, so that you can make shapes, or truffles whilst maintaining that shiny glossy look of tempered chocolate. And let me tell you, it’s quite tricky! The idea is to melt the chocolate enough to disrupt all the crystals, then to cool it to just the temperature where the beta crystals will readily form, and then raise the temperature enough to melt any unstable crystals, but not so far as to melt the beta crystals.

As you can see from the photo, I was successful at least a couple of times. The particularly shiny finish is due to moulding the tempered chocolate in plastic moulds.
