This led to an indepth discussion/friendly argument as to what is the difference in jelly and jam.
So what is the difference?
According to wikipedia:
JamJam typically contains both the juice and flesh of a fruit or vegetable, although some cookbooks define it as a cooked and jelled puree. In the US, the term "jam" refers to a product made of whole fruit cut into pieces or crushed then heated with water and sugar to activate its pectin before being put into containers
JellyIn the U.S. and Canada Jelly refers to a clear or translucent fruit spread made from sweetened fruit (or vegetable) juice and is set by using its naturally occurring pectin, whereas outside North America Jelly refers to a gelatin-based dessert. Additional pectin may be added where the original fruit does not supply enough, for example with grapes. Jelly can be made from sweet, savory or hot ingredients. It is made by a process similar to that used for making jam, with the additional step of filtering out the fruit pulp after the initial heating.
According to wikipedia both of these are variations of "fruit preserves".
So it seems the primary difference is the existance of the flesh of the fruit. Simple enough!
In the end we agreed it depends on how you intend to eat the "fruit preservers" but most often we prefer jam. The more complicated decision is which flavor.
Which do you prefer?
And what is your favorite flavor?
