The great thing about Rogan Josh is that it is best made ahead so easy to serve for guests. Rogan means “fat” and josh means “heat” or “intensity”. This dish was traditionally made with fatty meat on the bone, slow cooked for flavour. In these more health-conscious days, I like to use trimmed lamb shoulder, lamb leg, or even lamb leg or grilling chops. I have used a combination of spices to get an authentic flavour, although you could easily use a commercial Rogan Josh paste if you prefer. While spinach is not traditional in Rogan Josh, I love to stir it through for colour and to add another vegetable.
