Yellow lentils finished with spices bloomed in hot ghee and poured over at the table.

Dal tadka is cooked lentils given a tempering — whole spices fried in ghee until they crackle, then poured over the pot at the last moment. The tempering is not a garnish: it is where most of the flavour comes from, and it is added late precisely so the aromatics do not have time to cook away.
Tadka, also called chhaunk or phoron, is a technique rather than a recipe, used across the whole subcontinent and applied to far more than lentils. Frying whole spices in hot fat extracts the oil-soluble compounds that water-based simmering cannot reach, which is why the same lentils taste flat before the tempering and complete after it.
Dal is poured over rice rather than eaten alone from the bowl, though a thin dal is sometimes drunk at the end of a meal. Take only as much rice as you will eat in the next few mouthfuls and pour over that. With bread, use the bread to scoop rather than dipping the whole piece. A squeeze of lemon at the table lifts a dal that has been sitting, which is why the wedge is served rather than stirred in.
Simmer the dal with turmeric, salt and water until completely soft and beginning to break down — around thirty minutes in a pan, or three whistles in a pressure cooker. Undercooked dal cannot be rescued by the tempering.
Beat the cooked dal briefly with a whisk or ladle to an even, pourable consistency, adding hot water as needed. It should coat a spoon but still run off it.
The fat must be properly hot or the spices will stew instead of crackling. Test with one cumin seed — it should sizzle immediately.
Mustard seeds first, then cumin, then the dried chillies and garlic, then asafoetida last. Each has a different tolerance for heat, and adding them together means either burnt garlic or raw mustard. The whole sequence takes under a minute.
Stir in the chopped tomato and Kashmiri chilli and cook for two minutes until the tomato softens and the fat turns red.
Tip the whole tempering into the dal and put the lid on at once for two minutes so the aromatics are trapped rather than escaping into the kitchen. Finish with coriander and a squeeze of lemon.
