Common trimming steps for cauliflower and cabbage include removing the outer leaves, trimming the stem, and coring the head. For cauliflower, separate the florets.
When preparing cauliflower, start by removing any tough or discolored outer leaves. Then, trim the stem, leaving a small portion attached to the head. To separate the florets, use a paring knife to cut them away from the central core. Aim for florets that are roughly the same size for even cooking.
For cabbage, begin by removing the outer leaves, which are often damaged or wilted. Trim the stem close to the base of the head. To remove the core, cut around it with a paring knife at an angle, then pull it out. You can then shred, slice, or chop the cabbage as needed for your recipe.
To prevent cauliflower from browning during cooking, add a tablespoon of lemon juice or vinegar to the cooking water. This helps maintain its bright white color.
