This mild and flavourful dish comes from Julie Sahni's 1980 book, Classic Indian Cookery. She adapted it from a dish served at the Akbar India Restaurant in New York City (which I think is now closed). I am posting this for some former exchange students who are going through severe Kabuli withdrawal. I often make this a day in advance. A few comments. I think Julie Sahni writes some of the clearest recipes on the planet -- and she does so without being patronising. Check out her books (and note that I have abbreviated some instructions slightly). Also, I wonder if Kabuli means the recipe is influenced by dishes from Kabul, Afghanistan. Finally, I have never timed this accurately, so the prep time is a bit of a guess.
