How do broccoli crowns differ from a whole head?

Crowns are the florets and upper stem with most of the thick stalk removed. You get less waste and less prep, but you pay for trimmed weight rather than stalk.

How should I store them?

Keep them unwashed in a loosely open bag in the refrigerator crisper drawer. Use within a few days; yellowing florets or a strong smell mean they are past their best.

What is the best way to cook them?

Steam or blanch for a few minutes until bright green and just tender, or roast at high heat with oil. Brief cooking keeps the texture firm and limits the sulfurous smell of overcooking.

Yes, but blanch first for about two to three minutes and cool in ice water. Freezing raw crowns turns them mushy when thawed.

Are they good for you?

Broccoli is high in vitamin C, vitamin K and fiber, and low in calories. Cooking methods that limit water loss, like steaming or roasting, keep more of the water-soluble vitamins.
