Reduce heat to low, partially cover and simmer until peas are very tender, about 30 minutes. Drain. (Alternatively, pressure cook dal with 2.5 cups water in a pressure cooker or an Instant Pot. If you are using a pressure cooker, cook the dal till the vent goes off twice)
In another large saucepan, toast cumin and coriander seeds over medium heat, stirring, until fragrant, about 3 minutes. Transfer to mortar and grind to a powder.
In same pan, heat clarified butter over medium heat. Add onion and cook, stirring, until softened, about 3 minutes. Add garlic and ginger and cook, stirring, for 1 minute. Stir in salt, chile powder to taste, turmeric and reserved cumin mixture. Season to taste with black pepper.
Stir in tomatoes and juice, and bring to a boil. Stir in drained cooked split peas, stock and lemon juice. Reduce heat and simmer until flavors are melded, about 5 minutes.
Add spinach, in batches, stirring to submerge each before adding the next. Cover and cook until spinach is wilted, about 5 minutes.
