Delish! Fabulously rich and decadent. I checked with SolightlyUK and substituted a good-quality dark chocolate for the one specified, since I don't have a Waitrose branch near me. The chilli flavour is subtle (at least with the variety of chilli that I used) - in fact, I'm not sure people would guess what it was if they weren't told. The chocolate mixture is rich and decadent, thickening into a glossy bliss as it reheats. So good, you have to try it!
