Salting to draw the water out 41 recipes

• Salted evenly over every surface rather than tipped on in one place and tossed once.
• Laid out so the water has somewhere to go: a colander, a rack, or a sieve over a bowl, never a flat dish where it sits back in what it gave up.
• Given real time, and there is visible liquid to show for it: a pool underneath, a drip, or a wrung handful.
• That liquid is removed. It is squeezed, blotted or poured away, and the food is dry to the touch before it goes anywhere near heat.
• The dish is seasoned knowing salt has already gone on, tasted before any more is added.

Where it goes wrong It went into the dish still wet, and was salted again out of habit. The water it was carrying dilutes and steams whatever it meets, so the result is watery and over-seasoned at once, and those are two faults that cannot be corrected in the same direction.

Reducing a sauce 95 recipes

• A steady simmer with the surface moving, never a rolling boil that throws it up the sides and scorches what is left on the base.
• Judged by behaviour rather than the clock: it coats the back of a spoon and holds a clean line when a finger is drawn through it.
• The drop in volume is visible against the side of the pan: there is a line to see, not a guess about whether anything has happened.
• Seasoned at the end and not the beginning, because salt concentrates at exactly the rate everything else does.
• Nothing is catching underneath: a spoon drawn across the base comes up clean, with no browned film building where the heat is fiercest.

Where it goes wrong It was seasoned at the start and then reduced by half. The salt concentrated along with everything else, so the sauce reaches perfect body and is too salty to serve. And the only remedy is to dilute it and reduce it all over again.
