These swaps come from the substitution list Well Stockd uses to match recipes to your kitchen, last updated . We remove swaps known to be unsafe, but not every swap has been tested in a kitchen, and a swap is cooking guidance, not an allergen or nutrition equivalent. Check labels and what the recipe needs before substituting.
