Question 1

Does marinating actually tenderise meat?

Accepted Answer

Barely. Marinades add **flavour to the surface** and do very little to tenderise, and they penetrate far less than almost everyone assumes.

**How far a marinade actually reaches.** Testing consistently finds penetration of only a **few millimetres** even after many hours. Meat is largely water and protein, and a marinade must diffuse through a dense structure — it does not soak in the way the word implies. Overnight marinating produces meat with a well-seasoned outside and an unchanged interior.

**Salt is the exception.** Salt ions are small and genuinely migrate through meat over time, which is why **brining** works and why a marinade's main effect is frequently just its salt content. If a marinade improves texture, salt is usually why.

**What about acid?** Marinades commonly contain lemon, vinegar or wine on the theory that acid tenderises.

Acid does **denature** surface proteins — but the result is not tenderness. Prolonged acid exposure makes the outer layer **mushy and then firm and dry**, because denatured proteins squeeze out moisture. Ceviche demonstrates this: acid changes the texture visibly, and it is not tenderising in any useful sense. Long acidic marinades commonly make meat worse.

**Enzymatic marinades** — pineapple, papaya, kiwi, fig — contain proteases that genuinely break down protein. They work, and they are **hard to control**: left too long they turn the surface to paste. Useful in short applications.

**Dairy and yoghurt marinades**, traditional in South Asian cooking, appear to work more gently, with calcium and mild acidity producing better results over longer periods.

**What actually tenderises:**

**Cut selection** — the largest factor by far.

**Mechanical breakdown** — pounding, scoring, or a needle tenderiser, which physically severs connective tissue.

**Slow moist cooking** to convert collagen to gelatine.

**Salt, given time.**

**Correct cooking and resting**, since overcooking is the usual cause of toughness.

**Slicing against the grain**, which shortens muscle fibres and does more for perceived tenderness than any marinade.

Question 2

What does acid actually do in cooking?

Accepted Answer

Far more than make things taste sour. Acid performs several distinct chemical jobs, which is why a squeeze of lemon improves dishes that taste nothing of lemon. Balancing flavour. Acidity cuts

Question 3

Does searing meat seal in the juices?

Accepted Answer

No. It is one of the most persistent cooking myths, it was tested and disproved well over a century ago, and searing is still worth doing — for an entirely different reason. Where the myth came from.

Question 4

Why do different cuts of meat need completely different cooking?

Accepted Answer

Because the answer is determined by how hard the muscle worked — and that single fact predicts the connective tissue content, which predicts whether the cut wants fast heat or long slow heat. The

Question 5

What does dry-ageing actually do to beef?

Accepted Answer

Three things simultaneously — enzymatic tenderising, moisture loss and flavour development — and only the first happens in wet-ageing, which is why the two produce genuinely different results. What

Question 6

What is the difference between curing, brining and smoking?

Accepted Answer

All three are preservation techniques that became flavour techniques, and they are frequently combined — but they do different things. Brining soaks food in a salt solution, usually for hours rather

Question 7

What does resting meat actually do?

Accepted Answer

It lets the temperature even out and the muscle fibres relax, so that less juice runs out when you cut it. The common explanation — that juices "redistribute" or get "reabsorbed" — is a
