Knife Skills: The Four Cuts That Cover Almost Everything

Prep time is where most weeknight cooking goes wrong. A recipe that claims fifteen minutes takes forty because dicing an onion takes four minutes instead of forty seconds. The gap is almost never the knife itself.

Hold the knife properly first

Most people grip the handle like a hammer. The control grip is different: pinch the blade itself between thumb and the side of your bent index finger, just forward of the handle, and wrap the remaining three fingers around the handle. It feels wrong for about ten minutes and then feels like the only sensible way to hold a knife.

This grip moves the pivot point forward, which gives you control over the tip and lets the knife rock rather than chop. Rocking is faster and quieter than lifting the blade clear of the board on every cut.

The claw is a speed technique, not just a safety one

Curl the fingertips of your guiding hand under, so the knuckles face the blade and the fingertips are behind them. The flat of the knife rests against your knuckles and rides along them. Your knuckles now set the thickness of every slice, which is why the claw produces even cuts as a side effect of being safe.

Cut one: the dice

Demonstrated on an onion, because it is the cut you will make most often. Halve the onion through the root, peel, and lay it flat side down. Make horizontal cuts toward the root without cutting through it, then vertical cuts the same way. Now slice across and the dice falls apart on its own. The root holds everything together until the final moment, which is the entire trick.

Cut two: the julienne

Thin matchsticks, used for carrots, peppers and anything going into a stir-fry or a pickle. Square off the vegetable into a rectangle first, discarding the rounded edges, then slice into thin planks, stack the planks, and slice again lengthways. Squaring off feels wasteful and is what makes the cut consistent.

Cut three: the chiffonade

For leafy herbs and greens. Stack the leaves, roll them into a tight cigar, and slice across into thin ribbons. Use a sharp knife and a single decisive stroke; sawing bruises basil and turns the cut edges black within minutes.

Cut four: the rough chop

Deliberately imprecise, for things going into a stock, a soup that will be blended, or a long braise. Knowing when precision does not matter is as useful as being able to produce it, and it saves several minutes on every pot of soup.

A dull knife is the dangerous one

A sharp knife bites where you place it. A dull one slides off the skin of a tomato or an onion and into your hand, and requires more force, which means less control. Use a honing steel before each session to realign the edge, and have the knife properly sharpened two or three times a year.

Practise on cheap vegetables

Buy a bag of onions and dice all of them in one sitting. Freeze what you do not need. Twenty minutes of deliberate repetition will do more for your cooking speed than any equipment purchase.
