This is a special recipe because it's Dishoom's house black dal. If you've never been to this Bombay restaurant it's well worth checking out next time you're in Edinburgh, London or Birmingham. Drool-worthy, spice-kissed gorgeousness awaits!
Urad dal can sometimes be hard to come across but we found a giant bag of them in our local Asian supermarket, which supplies a lot of ingredients for Indian cooking. Urad dal is a small bean with a black outer coating and white inside that gets very creamy when cooked, giving the delicious thick texture to the finished dal.
