Liver — Liver and onions · 170

Cook Liver as Grilling to 78° at the centre. Plate as Liver and onions. Angle 4: check thickness before the clock. Among the densest sources of iron and vitamin A in the food supply — and among the strongest-flavoured. Freshness decides everything: the best pieces need only salt and sesame oil raw. Because vitamin A stacks up quickly, this is a cut to eat occasionally rather than often.

Bright cherry colour with a slight sheen and spring. Avoid dark, dull or waterlogged pieces. Raw liver only from a trusted same-day source. When cooking, take it until the red centre is gone; a twenty-minute milk soak softens the edge of the flavour. Vitamin-dense; buy bright and springy the day you cook.

Cook Liver as Liver and onions to 78° at the centre. Thick grain needs more time. A cut’s grain comes from how much the muscle worked. Liver needs heat through to 78° before “Liver and onions” makes sense. 78 is a stage of that heat, not a luxury score. The same cut becomes a stew, a grill, or a braise, so a steak minute does not cover a pot. Thick connective tissue wants time, not a hard sear alone. This is not medical advice.
