Cauliflower	3–5 daysfrom purchase	10–12 monthsfrom purchase

Fridge at 4 °C (40 °F) or colder, freezer at −18 °C (0 °F). Freezer times are for best quality: food kept frozen stays safe, but slowly loses taste and texture. These times are USDA guidance, not a guarantee. When in doubt, throw it out.

How to tell if cauliflower has gone bad

Small brown or gray spots on the florets are oxidation: shave them off. Large dark, soft patches mean rot.
A slimy or mushy texture.
Mold, often black or gray fuzz, or a sour, rotten smell.

How to store cauliflower

Keep the head unwashed in the crisper drawer, stem side up so moisture doesn't collect on the florets.
Leave it whole until you use it: cut florets spoil faster.
Wash it just before cooking.
Keep cut florets in a sealed container lined with a paper towel.

Can you freeze cauliflower?

Yes, for 10 to 12 months. Cut it into florets, blanch them for about 3 minutes, cool them in ice water, dry them well, then freeze them in a single layer before bagging. Cook from frozen: roast, steam, or add to soups, curries and gratins.
