After my not-so-successful attempt last week, I decided to try a different assembly this time. I have also discovered that “toffee sauce” does not freeze well and made a chocolate shell to encase it. Unfortunately I was a little lazy and ended up with a chocolate shell that is slightly too thick!
I still think it is an improvement though and more toffee and more coffee mousse and of course, chocolate. Chocolate is always good. I think the only change I’d make next time round would be a thinner chocolate shell and a thicker toffee sauce. Hmm. But until then, bon appetit!
