Storage tips:
Brussel Sprouts are a cool weather crop, and can keep anywhere from a few days to upwards of 5 to 6 weeks, depending upon the temperature and humidity at which they are kept. Ideal temperature is just above 32º F, in very high relative humidity (>95%). However, you must be extremely cautious as they freeze and damage quickly at roughly 31º F. At around 40º F, they will keep for about 2 weeks, and for only a few days at 50º F.
Waxy or shriveled outer layer(s) of leaves should be removed prior to preparing brussel sprouts.
