Tadka: blooming spices in fat 22 recipes

• The fat is at tempering heat before anything goes in, around 180C (350F): one test seed dropped in surfaces and cracks within two or three seconds. A seed that sinks and sits quiet means the fat is cold and everything will steep rather than bloom; fat already hazing and thinning has gone past 200C (390F), and the first thing in will be black before the last thing is in.
• Ask what went in and in what order, then read it back off the pan: the hardest seeds lead, with ten to twenty seconds before the next addition, and the softest seeds, any leaf and any powdered aromatic go last with only seconds left. Everything tipped in on one drop is a fail even when the pan smells right, because the most delicate thing in it cannot survive the time the hardest one needs.
• The pan gave a hard scatter of popping that rose, peaked and thinned before it left the heat. A pan that stayed silent never reached popping heat and the seeds are still hard and raw against the teeth; seeds still cracking loudly as it is poured finished blooming in the dish instead of in the fat, where nothing was watching them.
• Cumin is exactly one shade darker than it went in and no more, a warm even brown that smells nutty and sweet; anything near coffee colour, or smelling of scorch, has already carried bitterness into the fat. Fenugreek is pale gold, checked under the light with nothing copper or brown among it, and this is the mark to judge first: past gold it turns the whole pot bitter, and no salt, sugar or souring will pull it back.
• The leaf is blistered and gone translucent, still green at the edge and crisp rather than black or limp, and it cracked sharply when it met the fat. It reached the dish still at full heat and answered with a violent hiss, and it reads on the surface afterwards as bright separate fat with whole spices suspended through it, not a dull dark sediment settled on the bottom.

Where it goes wrong The fat was pushed past hazing before anything went in, or every spice was tipped in together, so the hardest and the most delicate cooked on one clock: in the seconds the hardest seeds need to pop, fenugreek goes from gold to brown and the leaf goes black. Nothing can be corrected after that. The tempering pours in dark and smells scorched over the top of the dish, the specks read black rather than brown when the surface is turned to the light, and a flat acrid bitterness arrives at the back of the palate after the swallow and stays there through the next mouthful.

Roasting in a hot oven 56 recipes

• The oven was fully up to heat before anything went in, given time beyond the indicator light rather than judged by it.
• Every piece has air around it. Nothing touches its neighbour and nothing is packed to the edge of the tray, because crowded food steams itself in its own moisture and never browns.
• Colour is even across the whole tray, the tray having been turned at least once: no pale row at the back and no dark row at the front.
• It came out BEFORE the target temperature, not at it. Carryover keeps driving the inside up by several degrees after it leaves the oven, and that rise is part of the cooking rather than an error in it.
• The temperature was read at the coldest part rather than the easiest one to reach, and read again after the rest.

Where it goes wrong The tray was crowded, or the oven was not truly up to heat. The food releases steam faster than a cool box can carry it away, so it sits pale and slack, and the extra minutes spent chasing colour take the inside well past where it should have stopped.
