Berry (botany) in fruit type may have led to the evolution of fruit eating in mammals and birds. Fruit type has been considered to be a useful character in classification and in understanding the phylogeny of plants. The evolution of fruits with a berry-like pericarp has been studied in a wide range of flowering plant families. Repeated transitions between fleshy and dry pericarps have been demonstrated regularly. One well-studied family is the Solanaceae, because of the commercial importance of fruit such as tomatoes, bell peppers, and eggplants or aubergines. Capsules, which are dry dehiscent fruits, appear to be the original form of
Fruit preserves spread made from sweetened fruit (or vegetable) juice—thus differing from jam by excluding the fruit's flesh—and is set by using its naturally occurring pectin, whereas outside North America jelly more often refers to a gelatin-based dessert, though the term is also used to refer to clear jams such as blackcurrant and apple. In the United Kingdom, redcurrant jelly is a condiment often served with lamb, game meat including venison, turkey and goose in a festive or Sunday roast. It is a clear jam, set with pectin from the fruit, and is made in the same way, by adding the redcurrants
