Frequently asked questions
How do I chop tomatoes without crushing them?
Use a sharp blade grid and a firm, quick press so it slices cleanly rather than squashing. Firmer, less ripe tomatoes also dice more neatly.
What dice size is best for salsa?
A fine to medium grid gives salsa its texture. Many choppers include more than one grid, so you can match the dice to the recipe.
