Spread the word, people: While both may taste great on your morning toast, jelly and jam are not the same thing. The central difference is the form of the fruit. Jelly is made from fruit juice, while jam is made from crushed fruit, resulting in a less stiff, less gel-like texture. So, in the never-ending battle of food cred, because it has bits of fruit in it, jam is the winner (though for a PB&J, it’s hard to beat jelly).
