Key Differences

Jam is made by crushing fruit and cooking it with sugar, resulting in a thick, spreadable mixture. Conserve typically involves multiple fruits, sometimes combined with nuts or raisins.
The texture of Jam is generally uniform and smooth, with bits of fruit pulp. Conserve has a chunkier texture due to the inclusion of whole fruits or large pieces.
Jam is often used as a spread for bread or pastries. Conserve can be used similarly but is also popular as an accompaniment for meats or cheeses due to its varied texture and ingredients.
The cooking process for Jam usually involves boiling the fruit until it reaches the desired consistency. In Conserve, fruits are often cooked separately and then combined, maintaining some distinct flavors.
While Jam is typically made with one type of fruit, Conserve is a more complex preserve that offers a blend of different fruit flavors and textures.
