I don't know what I did wrong, but how could I ever face Mary and Paul with these monstrosities? This is a new baking low. I won't give you the recipe because it obviously doesn't work, but I will tell you that chilli chocolate ganache and white chocolate and lime ganache are both AMAZING and I have enough left over to either attempt macaroons again or make chilli and lime truffles. So I'll give you the recipes for those.
Chilli chocolate ganache:
180ml double cream
160g chilli chocolate
Melt the chocolate in a ceramic bowl over a pan of barely simmering water. Once completely liquid: add the cream, stir until combined completely and leave to cool until set to a spreadable rather than pourable consistency. If desired add some chilli flakes but be careful! You want a touch of heat, not to blow someone's head off.
Lime and white chocolate ganache:
120ml double cream
140g white chocolate
zest of 1 lime
juice of half a lime
Use the same method as above, adding the juice and zest to the chocolate and cream mixture.
