In Donal's own words, 'I’m a self taught home cook who writes and photographs food for a living. I’ve been cooking from an early age ...
180 g sugar
200 ml double cream
200 ml golden syrup
1 tblsp cocoa powder
2 tblsp butter
Mix the sugar, double cream, syrup and cocoa powder into a heavy based pot with high sides.
Bring to the boil without the lid and stir occasionally until it reaches 122°C on a candy thermometer, or test it by pouring a few drops of the mix into a glass of ice cold water and move the glass to form a small ball. If it's done, it should stay in the ball shape and be really hard. Cooking time: approximately 15-20 minutes.
Add the butter and stir through.
Pour the mix into a jug with a fine spout then pour it into tiny cake cases (about 2cm in diameter)
Leave the mixture to cool completely and store in the fridge.
