Garlic, 1/2 lb. This garlic is fully cured and should last for at least a couple of months; ideal storage conditions for cured garlic are 33 degrees with low relative humidity, around 60-70 percent. Keep in your fridge as long as it has low relative humidity! Otherwise, keep in a dark, cool, well-ventilated spot. 1/2 lb. is typically 3-5 whole heads of garlic depending on the size.
