A whole head of cauliflower costs a fraction of pre-cut florets, keeps twice as long, and takes about ninety seconds to break down once you know where to put the knife. The secret that most people miss: all the work happens at the stem. Attack the core, and the head practically falls apart into perfect florets on its own — no white confetti all over the counter.
Start Clean
Take the head out of its packaging and give it a quick rinse under cold water, shaking out what collects between the branches. Pull off the outer leaves — they twist away easily. (Do not toss them: the leaves are delicious roasted with olive oil and salt.)
The Core Method
Flip the cauliflower stem-side up. With a paring knife, cut a shallow cone around the central stem, angling the blade in toward the core. Go a little deeper on each pass, and use the back of the knife to push and loosen as you work your way around. Once the core comes free, the main branches are exposed and most florets separate with your hands alone — that is the whole trick. Snapping instead of slicing keeps the florets whole and the crumbs to a minimum.
Anything still attached gets a quick flick of the paring knife at its base. Cut the head into quarters first if you prefer working flat on the board; the core lifts out of each quarter with one angled slice.
Sizing Your Florets
Whatever you are cooking, cut florets to a uniform size so they finish together. For roasting, keep them large — about two inches — so they brown before they soften. For steaming or blanching, medium is right. For rice-sized cauliflower, skip the knife after separating and pulse the florets in a food processor.
Use Every Part
The core is completely edible — peel its tough exterior and slice the sweet interior into stir-fries, or simmer it into soup. Leaves roast into crisp chips. A single head, fully used, stretches across two or three meals.

FAQ
How do I stop cauliflower crumbs going everywhere?
Cut from the stem side and snap florets apart instead of slicing through the tops. The crumbs come from cutting across the curd.
How long does cut cauliflower keep?
4–5 days in a sealed container in the refrigerator, with a paper towel inside to catch moisture. Whole heads keep up to two weeks.
Can I freeze it?
Yes — blanch florets 3 minutes in salted boiling water, shock in ice water, dry well, and freeze flat on a tray before bagging. Good for 6 months.
What are the brown spots on my cauliflower?
Oxidation — harmless early on. Shave them off with a paring knife. If the spots are soft, wet, or smell off, the head is past its prime.
