Fiery richness

I cooked a chili last night. This is a really simple thing to make, but it is a rich, satisfying meal. You can also cook enough so that there is some left for lunch the next day.

Key ingredients in a nice, but I am sure completely non-traditional, chili are:
Streaky bacon; quite a lot of this, fried before adding to the chili
Plenty of fried onion
Dark chocolate; a few squares, I have some 85% stuff that works fine.

The chocolate adds richness and complexity to the flavour. It was really nice.
