Strawberry preserves (the stuff with big strawberry chunks in it) are probably my "go to" flavor, but I love lots of other ones too. Orange marmalade is up there, along with lemon curd, and I can't resist a nice thick guava jelly. There are other flavors I like too, but those are at the top of the list. The only thing I don't like is actual jelly. I don't want jellied fruity sugar water. I want it to feel like there's real fruit in it. The only exception is grape. I really like the new Welch's Natural Grape Spread (without HFCS).
I've had bad luck with strawberry because my favorite brand (Smuckers strawberry Simply Fruit) changed their recipe and started making it MUCH thinner with NO fruit chunks and it was very disappointing. I was a loyal customer of theirs for ages until that happened. I tried their organic strawberry but it was ridiculously sweet and I couldn't even finish the jar. Then I spent a long time trying every brand I could find, without any success! They were all unacceptable in one way or another. Finally, my mom showed me how to make my own, and my search ended.
