Rinse the split peas: Wash thoroughly until the water runs mostly clear. Soak for 30 minutes if you have time (optional, but helps them cook faster).
Toast the spices: In a large pot, heat ghee or oil over medium heat. Add ajwain seeds and (if using) mustard seeds. Let them sizzle and pop for 20–30 seconds — don’t let them burn.
Sauté the base: Add chopped onion and garlic, and cook until translucent. Stir in turmeric and ground coriander, let it bloom for a minute.
Add veggies & peas: Stir in the carrots, potatoes, and drained split peas. Mix well to coat everything in the spice mixture.
Simmer: Pour in the water or broth, bring to a boil, then lower to a gentle simmer. Cover partially and let cook for 40–60 minutes, stirring occasionally, until peas and potatoes are soft and everything has melded together.
Adjust seasoning: Add salt and pepper to taste. If the stew gets too thick, add a splash of hot water to loosen it.
To Finish: Stir in a bit of fresh parsley or chopped coriander
Drizzle with ghee or a squeeze of lemon for brightness
Serve with crusty bread, flatbread, or over rice
