I have one on the go now.
Added the chilli of course but note the bbc recipe say to add 1 tsp each of paprika and cumin ......which I have never thought of.
What think you ?
Always Paprika both smoked and regular and Cumin. Also add Fennel. The Cumin and Fennel both as part-ground seeds to give that little hit of flavour every so often.
Recently (after reading a guardian article) am now adding the espresso grounds from my Gaggia - imparts extra richness as does good dark chocolate.
A splash of Soy sauce, Lea and Perrins or Mushroom ketchup adds extra umami.
I also favour a high ratio of beans* to meat.
Some Oregano near the end finishes it off nicely :-)
I assume Chilli (homegrown is best) is already part of the mix….
*Home prepared kidney beans are faaaaar superior to canned jobbies….
