Prep once, eat all week
The point of a matching set is a system. Cook in batches on one day, portion straight into glass while it is still warm, cool it uncovered for a few minutes, then seal and shelve. Clear glass means you can read the fridge at a glance, and graduated sizes mean the half-portion nests behind the full one instead of sprawling across a shelf.
How long it keeps, and where
| Food | Fridge | Freezer | The habit |
|---|---|---|---|
| Cooked grains & pasta | 3–5 days | 1–2 months | Cool before sealing so steam does not pool on the lid |
| Cooked meat & poultry | 3–4 days | 2–3 months | Freeze in single portions; reheat with the vent open |
| Soups & stews | 3–4 days | 2–3 months | Leave a finger of headroom; liquids expand as they freeze |
| Cut fruit & salad | 2–3 days | Not advised | A paper towel in the base keeps greens crisp longer |
| Leftovers, mixed | 3–4 days | 1 month | Label the lid with tape; glass wipes clean after |
Times are general food-safety guidance, not a rule for a specific dish. When in doubt, trust your nose and the two-hour rule for cooling.
Freezer to oven, without the crack
Tempered and borosilicate glass takes big temperature swings, but glass still dislikes a sudden shock. Move a container from the freezer to the fridge overnight if you can, or let it stand ten minutes on the counter before it meets a hot oven. Put a glass base into a cold oven and let them heat together rather than into a screaming-hot one. Never set hot glass straight onto a cold, wet surface.
Microwave with the lid, not sealed
Reheat with the lid resting on top or the vent tab open, never latched tight: steam needs somewhere to go. The glass base is microwave safe; the lid is there to stop splatter, not to cook under pressure. For the oven, the lid comes off entirely.
Keep the seal sealing
- Wash lids on the top rack, or by hand if you want them to last even longer.
- Let the silicone gasket dry fully before you snap the lid on for storage.
- Store lids off, not clamped, so the gasket keeps its spring.
- When a lid finally stops sealing, replace that size rather than the whole set.
