Freezing reference · plainandfrugal.com/tools/free-food-preservation-toolkit · Chart updated September 13, 2026. Keep food frozen at 0°F (-18°C) or below. This chart summarizes preparation; use the complete method for cooling, packaging, and headspace. It is not a canning guide.
Method matters
Blanch vegetables; protect cut fruit from browning.
The National Center for Home Food Preservation says blanching is necessary for almost all vegetables because it slows enzyme action that harms flavor, color, and texture. For water blanching, start timing when the water returns to a boil.
Cool vegetables promptly after blanching, usually for about the same length of time, then drain thoroughly. For apple slices, measured ascorbic acid is an alternative to steam blanching. This tool summarizes freezing guidance; it does not make food shelf-stable and must not be substituted for tested canning instructions.
Read the NCHFP blanching guidance ↗Keep the freezer at 0°F (-18°C) or below. FoodSafety.gov explains that frozen-food storage limits refer to quality: food kept continuously frozen at 0°F or below can remain safe indefinitely, although quality declines over time.
