A fruit butter is a sweet spread made of fruit cooked to a paste, then lightly sweetened. It falls into the same category as jelly and jam. Apple butter and plum butter are common examples. Fruit pastes, popular in Latin American countries, are similar but more highly sweetened and jelled. They are sold in shallow tins or as wrapped bricks, while fruit butters usually come in wide-mouthed jars.
The fruit is cooked at first, but not too much, as the fruit will burn and soon lose its sugary taste. However, if done right, the newly made fruit butter or paste can have a texture similar to dairy butter.
