Learn The Delicious Differences Between Jelly, Jam, And Preserves

While 'preserves' can be a term used for all fruit spreads, the clarification here is that preserves are made up of large chunks of fruit cooked down with sugar, but they tend to be much less syrupy than other options. 

Jam is also made of mashed fruit and sugar, but with added pectin and fruit juice as well that gives it a little more clear, gel-like substance

Jelly is the most gel-like of the three as it uses more pectin than jam. It's also cooks down longer and goes through a thorough straining process to achieve that translucent appearance.
