Crab-apples are small, extremely tart fruits in the same genus as table apples, and some botanists believe that they may be the survivors of the wild ancestors of the domesticated apple. The fruits and their trees look remarkably like apples, which can lead to unfortunate confusion, as the taste of crab-apples is rather distinctive and often unpleasant on its own.
The Crab-apples consist of a genus of about 35 species of deciduous trees and shrubs from the woodland and thickets of Europe, Asia and North America. There are three species which can be seen on the walkway. In some species the fruit is astringent and acidic and is not palatable when raw. The place where crab-apples come into their own is crab-apple jelly. The small fruits are high in pectin, a natural fruit based gelatine, and when they are cooked with a liberal helping of sugar, they develop a rich, flavourful, very tart ruby red jelly which some consumers find quite delightful. Crab-apple jelly may be cut with other ingredients, or used plain. It is often paired with toast, scones, and other baked goods.
