Marinate

Steeping food in a seasoned liquid before cooking — which flavours the surface, and does far less to the interior than most recipes imply.

Why it works

The claim that a marinade penetrates deeply is mostly wrong. Flavour molecules are large and diffuse slowly through dense muscle; after several hours most have travelled only a few millimetres. Salt is the exception — it is small and ionic and does move inward, which is why the genuinely effective part of most marinades is the salt, and why a dry brine achieves much of the same result. Acid does something else entirely and is the part that goes wrong: citric or acetic acid denatures surface proteins in the same way heat does, so past a few hours the outer layer turns opaque, mealy and chalky, cooked without ever meeting a pan. Ceviche is that effect used deliberately. Enzymes in pineapple, papaya and ginger are more aggressive still and turn meat to mush within hours. Oil carries fat-soluble aromatics and helps them cling; sugar helps browning but burns.

How to tell

• The surface should still look raw. Opacity or a whitened edge means the acid has begun cooking it.
• Two to four hours is the working window for most acidic marinades; overnight belongs to salt-forward, low-acid ones.
• The meat is wiped nearly dry before cooking — a wet surface steams instead of searing.
• Non-reactive containers only. Aluminium reacts with acid and adds a metallic taste.

When it goes wrong

The outside is mealy and chalky after cooking.

Too long in acid. The surface proteins denatured before any heat arrived, and they will never take a proper crust.

The meat turned to mush.

Enzymatic marinade — pineapple, papaya, kiwi or ginger. These act fast and do not stop.

Burnt black patches and a bitter taste.

Sugar in the marinade, not wiped off. Sugars carbonise well below searing temperature.

No noticeable difference after marinating overnight.

Realistic. If the marinade had little salt, very little reached the interior. Salt is what makes marinating worthwhile.

Recovering it

Surface damage from over-marinating is permanent — trim it if it is thin, otherwise cook it and accept the texture. Mushy enzymatic damage is unrecoverable. Excess sugar can be wiped and blotted before the pan, which usually prevents the worst of the burning. The reliable habit is to treat the marinade as seasoning for the surface, and to salt separately and ahead if you want the interior seasoned.
