How to Store Brussels Sprouts
Brussels sprouts are at their best kept on the stem outdoors, rather than harvested and stored in quantity. The sturdy plants supply buttons from late autumn through winter, and a touch of frost often improves their flavour. Pick firm, tightly closed sprouts from the lower stem first, moving upwards as the season progresses.
Best storage conditions
Keep plants in their growing position in cool, moist winter soil, ideally around 0 to 5 degrees C, with open air circulation. They are hardy, but stake tall stems against wind and avoid waterlogged ground. A thick mulch can help keep soil workable during cold weather. Picked sprouts should be held only briefly at 0 to 4 degrees C in a humid refrigerator or frost-free, airy outbuilding, never in warmth.
How long it keeps
On the plant, sprouts can provide harvests for 3 to 5 months, depending on sowing date, variety and weather. Once picked, they are best used within several days and rarely keep well beyond a week. Frozen sprouts retain good cooking quality for many months when properly prepared and kept frozen.
Storage methods
Leave stems rooted in the ground and harvest a few sprouts at a time by twisting them downwards from the base of the stem. Remove yellowing lower leaves to improve airflow, but retain healthy foliage. In exposed sites, tie each stem to a stout cane or support. If severe weather is forecast, lift a few whole plants with roots and stand them close together in moist soil or sand in a cool, frost-free shed or garage. This is short-term insurance, not a substitute for outdoor harvesting. Keep only firm, unblemished sprouts and remove anything soft or mouldy.
Preserving
For freezing, wash sprouts, trim the bases and blanch them according to their size before cooling quickly and drying well. Freeze them loose on a tray first if preferred, then transfer to labelled bags for a chest freezer. Sprouts can also be shredded and frozen for quick cooking. Pickling is possible, but freezing gives a more familiar result and preserves their character better.
Tips
Do not strip every sprout from a stem at once unless necessary, as plants continue to stand well outdoors. Harvest after a dry spell where possible, because wet buttons spoil faster. Use loose, open sprouts first. Check staked stems after gales, as snapped plants deteriorate rapidly and should be harvested or frozen without delay.
