Finally had some time to make Eamon Sullivan's 10/10 chocolate delice (with salted caramel). It may seem like a lot of components but they were pretty straight forward. I didn't make the salted caramel but I thought the result was quite good without it.
I recommend halving the biscuit because you don't need that much. Or you can just re-rolled the dough and made biscuits like I did.
Before making it, just make sure to read the recipe thoroughly a couple of times.
