I’d tasted dals from time to time in Indian restaurants and liked them, but never had the occasion to cook one. I guess I was intimidated. What were dals even made of? And how many kinds were there? It seemed like dozens,maybe even a hundred. I asked my Indian friend, Shweta Galway, if she’d show me how to make one. She said yes, although she had a funny reaction, like I asked her to show me how to make a glass of milk.
