What it is

Cauliflower (*Brassica oleracea* var. *botrytis*) is a variety of cabbage in the Brassicaceae family. The edible part is the immature flower clusters and fleshy stalks, often called curds or florets. White is the most common colour, but green and purple varieties are also available.

Why it matters

Cauliflower is a versatile, low-calorie vegetable — about 25–27 calories per cup of raw chopped florets. It provides vitamin C, vitamin K, folate, and fiber, supporting general nutrition. It's also a popular low-carb substitute for rice, mashed potatoes, and pizza crust.

Key details

Common cooking methods include steaming, roasting, boiling, sautéing, grilling, or eating raw. Cauliflower rice is made by pulsing or grating florets into rice-like pieces. In Canada, it's widely used in roasted dishes, soups, and low-carb recipes.
