Well, this is a strange one. The recipe comes from John Whaite’s Perfect Plates in 5 Ingredients, and whilst it looks like a run of the mill chocolate cake, one of these five ingredients is definitely not like the others. Yes folks, this cake really does include a tin of condensed tomato soup.
It would be fair to say I was very suspicious when making this, and the smell of tomatoes whilst making the mixture was much stronger than I had imagined – although I did use a bit too much soup (the tin we bought was bigger than the quantity required and I only spotted just before the last drops went in!). Once the cake batter is made it goes into two sandwich tins and bakes in the oven for about half an hour – and out comes chocolate cake! Quite an attractive looking one, too.
Meanwhile you make some chocolate icing/ganache from a mixture of water, cocoa, butter and muscovado sugar. I found that the quantities in the recipe produced about 25% more than I needed. However, I did find icing the cake to be quite tricky because both my sponges were quite domed, and when I assembled the cake the top sponge broke up a little bit – the icing ended up being more of a glue to hold the whole thing together.
The resulting cake is really nice, really rich and really fudgey. I’m not sure whether that’s due to the tomato soup, or if it’s the massive (and I do mean massive) quantities of sugar and cocoa used in the cake. Are they there in their own right, or to mask the flavour of tomatoes? I’ve no idea, but the cake will be demolished by us two I can assure you of that.
