There are ten cups (2.35 L) of thick wine red sauce made from Dolgo crab apples in this bowl from one of my four small trees. The Dolgo makes 1 to 1.5 inch yellow fleshed apples with dark red skin. The flavor of the apples is very tart and the fragrance aromatic. Dolgo crab apple sauce is good alone if you like sour foods (I eat them right from the tree). It can be mixed with bland or sweeter or less colorful apples to perk them up. Ambitious people make jelly from them.
