When I decided to make these I had three requirements of my chosen recipe - that it contained chocolate, that it was reasonably portable and that it used up the half tin of chestnut purée in the fridge. I was making a dessert for New Year's Day, but the children would be taking home any leftovers, as we still have tons of Christmas goodies to finish up!
Brownies seemed the obvious answer, but my previous attempt at chestnut brownies (Dan Lepard's recipe) used whole chestnuts rather than purée, and weren't loved by everyone here. Choclette, at Chocolate Log Blog, had adapted Dan's recipe to use chestnut purée, and I made slight adaptations to her recipe which I hoped would make the result more chewy and brownie-like, rather than melt in the mouth.
I upped the sugar content, as I like sweet chewy brownies (and I was using unsweetened purée) and reduced the chestnut purée (to use the amount I had available!). Choclette often bakes with duck eggs, but I used large hen's eggs, keeping the number at two, in the interests of getting the more cake-like
texture I wanted. I also baked in a smaller pan to give deeper brownies. So, I used:
175g butter, 200g 70% plain chocolate, 225g dark muscovado sugar, 200g unsweetened chestnut purée, 2 large eggs, 100g spelt flour
The brownies weren't quite the texture I'd hoped for - I'd call them truffle-like - so I didn't quite achieve what I wanted, but they made a great dessert, eaten with whipped cream! After cutting, I was worried that they would be too fragile to pack up and transport, but they firmed up a lot as they cooled completely. I don't think unsweetened chestnut purée has as strong a flavour as sweetened, so here the chestnut was very much a subtle backnote, rather than a predominant flavour.
I still didn't manage to get many good photos, and all the leftovers went home with FB and CT, so there was nothing to photograph the next day, either! Poor light is one of the curses of winter baking!
