Blueberries

Blueberries have small seeds and coarse, tough skins. They contain very little acid, but are excellent for pies and sauce. However, they will make jelly very well if there are a few partly ripe berries among them, and their flavor is improved if some fruit containing acid is added to them. To prepare them for use, whether they are to be served raw or cooked, look them over carefully in order that all green or spoiled ones are removed and then wash them well in cold water.
