The Basic Chopping Motion: The Rocking Technique
When chopping with a chef’s knife, moving forward while rocking the heel of the blade up and down without lifting its tip from the board is the most efficient and safest method. Keeping the tip in place makes the blade pass through the same point each time, which makes chopping both faster and more even.
What Is a Coarse Chop, and When Is It Used?
A coarse chop consists of fairly large pieces that are not exactly the same size; it is preferred for vegetables that will be boiled for soup or stock and then strained or blended. Piece size does not matter here because the vegetables will either be removed or fully puréed.
What Is a Fine Chop, and When Is It Used?
A fine chop requires small pieces of similar size. It is used in dishes where appearance and even cooking matter, such as salads, appetizers, or a quick sauté. The more evenly the pieces are cut, the more likely they are all to cook at the same time and look neat on the plate.
How to Chop an Onion, Step by Step
Cut the onion in half without cutting through the root, then place the flat side on the board. Keeping the root intact, make a few horizontal cuts across the onion, then make vertical cuts toward the root. Finally, cut across them at a right angle to the root to create even cubes.
Leave the onion’s root end uncut until the very end; it holds the layers together and helps the onion stay intact as you chop it evenly.
Chopping and Crushing Garlic
Gently crush a garlic clove with the flat side of the knife to loosen the skin and make it easier to peel. After mincing it, keep the knife tip in place on the board and rock the heel back and forth over the garlic to bring it almost to a paste-like consistency; sprinkling a pinch of salt over it speeds up the process.
Chopping Herbs
When chopping herbs such as parsley and dill, gather the leaves into a tight bunch and rock the knife back and forth over them. Using a rocking motion instead of pulling the knife through lets you chop the leaves finely without crushing them. Crushed herbs darken quickly and lose their freshness.
When evenly cut vegetables cook over heat, all the pieces finish at the same time; with unevenly cut vegetables, some pieces may still be raw while others have burned.
How Chop Size Affects Cooking
Pieces of different sizes added to the same pan do not cook at the same rate: smaller pieces soften sooner while larger ones are still firm. That is why keeping ingredients cut to similar sizes when a recipe calls for them to be chopped directly affects the cooking result.
Common Chopping Mistakes
The most common mistake is pressing the knife straight down instead of rocking it; although this motion looks like it cuts the vegetable, it actually crushes it and leaves uneven pieces. Another mistake is lifting the knife tip off the board—lifting the tip creates a different angle and piece size with each stroke, leading to uneven chopping.
