How to Make It
In a medium saucepan, bring 6 cups of water to a boil. Add the split peas and a generous pinch of salt and boil until just beginning to break down, about 50 minutes. Drain well.
Meanwhile, in a large, deep skillet, heat the oil. Add the ginger, garlic, jalapeño, cumin and cayenne and cook over moderate heat until softened, about 6 minutes. Add the tomato and tomato paste and cook until the tomato is slightly broken down, about 5 minutes. Add the cream, butter and water and bring to a boil. Stir in the yellow split peas, chickpeas and kidney beans and season with salt. Simmer over low heat until thickened, about 15 minutes. Serve with basmati rice and naan.
