Adding cold yogurt directly to a simmering pan causes the dairy proteins to coagulate into unappealing curds rather than forming a smooth sauce. Temper the yogurt by whisking a tablespoon of the hot cooking liquid into the dairy before incorporating it off the heat. Blooming ground spices like curry powder in oil for 60 seconds draws out fat-soluble flavor compounds that water-based simmering misses entirely. Raw onions contain sulfur compounds that require gentle heat to break down into sweet, translucent rings without browning, which takes about 5 to 7 minutes in a wide skillet.
Multiplying recipe quantities requires adjusting surface area to maintain proper moisture evaporation rates during the 20-minute simmer phase. Doubling the cauliflower florets and lentils means water volume must scale sub-linearly, typically adding only 50 percent more liquid rather than doubling it, because a wider or deeper vessel retains steam more efficiently. Crowding a skillet drops the pan temperature below 212 degrees Fahrenheit, turning a simmer into a steam bath that prevents onions from softening properly. Batch-cook large quantities in a wide 12-inch Dutch oven to ensure adequate heat transfer across the base.
