Safe Substitutions in Canning Recipes
One of the biggest canning misconceptions is that small tweaks donât matter, but in canning, some changes affect safety while others only affect flavor. You can safely reduce or omit salt, swap pickling salt for kosher or sea salt, adjust dried spices and herbs, and often reduce sugar in fruit, pickle, or tomato recipes. Sugar and salt mostly impact taste and texture, not safety. You can also add extra bottled lemon juice if desired, since bottled juice has standardized acidity. What you canât safely change are ingredients or methods that affect acidity or density. Fresh lemon or lime juice canât replace bottled, fresh herbs shouldnât be swapped for dried, and low-acid ingredients like onions, peppers, garlic, squash, or extra vegetables shouldnât be increased beyond what a tested recipe calls for. Avoid adding thickeners like flour or cornstarch before canning, and never change jar size, processing time, or canning method. When in doubt, ask yourself: does this change acidity, thickness, or the amount of low-acid food? If yes, itâs best not to tweak it. If youâve got a recipe youâre unsure about, drop it in the comments. Weâll walk through whatâs safe together.
