Too Much Salt
If you’ve added too much salt to a recipe, there are several solutions, 1) add a little sugar. 2) in soups or stews, a raw potato slice added to the mixture will absorb the salt, and 3) a second batch can be made, omitting the salt, and added to the first batch. Combine the two mixtures and freeze half for later.
Add some salt, or, if the recipe is a vegetable or main dish, a teaspoon of vinegar.
Gravy Too Pale
First to be sure to brown the flour well before adding any liquid, which will also prevent lumps. If the gravy is still too pale, add a few drops of gravy base or soy sauce.
Gravy Too Thick
If your gravy is too thick then add a little more liquid.
