Our absolute favorite is the Boysenberry Preserves from Knotts Berry Farm.
Sooooooo yummy!
But we can never find it and don't plan on going back to that park anytime soon, so we settle for raspberry preserves.
To me, jelly is to gel-like, and DH hates the seeds that come in jam. So a preserve has the thicker jam consistency, but without the seeds. The whole family is happy!
