Gluten free chocolate chestnut cake

In the past, Tim's seemingly constant twittering used to drive me so nuts that on one occasion I physically removed his iPhone from him and threw it away. (He couldn't understand why I objected so vehemently to him tweeting people he didn't even know while we were out to dinner, in bed, or on our wedding day.) He doesn't have time for it as much these days which is excellent, and there have been far fewer phone related incidents in our home as a result.

I actually do have a twitter account. It's a fairly recent thing and I joined up initially to see what all the fuss was about. My personal experience is that it's something to do to take a break from other tasks or when I'm procrastinating from study. You can steal a moment on Twitter and read about the second-to-second happenings of people you don't know, or post your own. For example: 'Kitchenmade is bored and needs another coffee.' Thrilling stuff.

All of that aside, if you can get past the inanities, tantrums, spruiking of products and people who tweet every five seconds, there is some good stuff to be found via Twitter. It turns out that there are a lot of like-minded people out there who just love food and cooking and sharing their recipes and knowledge. For me, it's been a good way of keeping up with what's going on in the foodisphere.

The point of all of this is that a few days ago, I was on Twitter and I saw a post that caught my eye with two key words: 'chocolate' and 'chestnut'. Following the link, I found a recipe that I just couldn't go past for a gluten free chocolate and chestnut cake. I've been wanting to do something like this for ages and this looked simple and delicious. It got extra ticks because it's gluten free and because chestnut is the best nut you can eat due to it's zero fat content. In fact, as far as chocolate cakes go, this is about the healthiest I've ever seen without compromising on taste. The result is a smooth, moist texture, and just enough sweetness to make it rich without being sickly. I honestly cannot remember the last time I enjoyed a cake so much.

Now as always, I deviated slightly from the original recipe. First, I added rum. Second, I didn't have a spring-form square tin so I lined a small tray with baking paper and it worked just fine. However, I'm making this again for a dinner party on the weekend and it will be in regular round tin form. I also used a slightly different method which I've described, below. Finally, I glazed it with a dark chocolate-butter-coffee combo, but I wouldn't do that again because you just don't need it.

Ingredients
425g chestnut puree (I used a full 439g tin)
250g 70% cocoa chocolate (I couldn't get it so used 63% which was fine)
125g butter (I used unsalted)
6 eggs, separated
1 tsp vanilla
1 tsp rum
60g caster sugar
25g brown sugar

Preheat oven to 180ºC

In a food processor combine chestnut puree, butter, egg yolks and vanilla.

Melt the chocolate and let it cool slightly. Add it to the chestnut mixture, making sure it's well combined. You might need to stop and scrape down the sides of the bowl occasionally. When done, place the mixture into a large bowl.

Whisk the egg whites until doubled in volume and fluffy. Add the caster sugar bit by bit and continue to whisk until you get a glossy, stiff mixture. Sprinkle the brown sugar on top and stir through gently. I just turned the electric mixer down low for this bit.

Add the meringue mixture to the chestnut mixture a little at a time and fold through gently. I used a hand whisk. Pour into the prepared tin and bake for 40 minutes.

When it's cool, remove from the tin and dust with cocoa, icing sugar or glaze if you really want to.
