title: "How to Use Reusable Silicone Bags"
lead: "Fill the bag, press out the air, and seal the top firmly closed — they store food in the fridge or freezer, hold marinades and sous-vide, and most are microwave-, boil-, and dishwasher-safe. Wash and dry them fully open so no water hides in the seal."
recommendation:
  name: "Press out the air and seal firmly; use them fridge-to-freezer-to-microwave, and dry them fully open to prevent mold"
  reason: "A reusable silicone bag replaces disposable zip bags and does more, since food-grade silicone handles both freezer cold and boiling or microwave heat — one bag stores, freezes, reheats, and even cooks. To seal it, fill below the fill line, press or roll the air out, and close the top strip firmly along its whole length, because a gap there is the usual cause of leaks. They're made for fridge and freezer storage, for marinating, and for sous-vide or reheating — check your bag's temperature rating, and vent it when microwaving. The one real chore is drying: wash with soapy water or on the top dishwasher rack, then prop the bag wide open, upside down, so it dries completely inside, since trapped moisture in a sealed bag grows mildew and odor; a wooden spoon or an upturned cup holds it open. Store them flat and open, not sealed shut, and they last for years."
