I don't think you will ruin the consistency. Just be sure to melt it - don't let it really cook any longer. (Does that make sense??) No simmering, I guess, is what I'm trying to say.

It may cool and re-jell pretty quickly so you'll really want to force it through a sieve with the back of a spoon or a rubber spatula, but if you won't eat it otherwise, I say give it a try.

I think it may be ruined by heating it. How about giving it away?

No it won't be ruined by heating....but I would add a few drops of water...or juice or something while heating to compensate for any liquid lost by heating.
Don't boil, just heat until it's liquid and squish it through a sieve. and know that you will end up with about half a jar of jelly.

Can you put it through a mesh strainer without heating it up again? That is what I would do and try to press it through with the back of a wood or metal spoon. I know how you feel. I love all the different berry preserves but hate the seeds too. Always getting stuck in my teeth. LOL

Thanks, everyone. I didn't think I would have to bring it to a boil, but heat it just enough that I could easily press it through a sieve. Just didn't know if it would re-set or stay runny. I suppose if it did, I could still use it for syrup.
Thanks again.

If it stays runny, it would make a great sauce base for fresh Peach Melba.

If it was set to begin with, heating won't harm the "set"...but if it depended on the presence of whole fruit for it's thickness, it may be thinner.
The recipe I use for fruit tarts calls for heating some jelly with some "eau de vie" of a complementary sort...like framboise for berries or peach brandy for peaches and brush it over the top of the fruit and drizzle around a bit....it re sets....if I haven't added too much of the booze...:)

Curious ? You started with Preserves. They have pieces of the whole fruit. The seeds are small.

Sounds like you would wind up with Rasberry Jam, instead of Preserves.?????

I wanted to know because, I'd like to remove the seeds also.
Lou

Yes, Lou, it turned out as a smooth jam. I don't mind seeds in some preserves, like strawberries, but raspberries and blackberries have me spitting seeds for(seems like)hours after eating. This turned out so well, I might be tempted to stock up on raspberry/blackberry preserves the next time I see them on sale.

Noinwi:
Thank You.
Why not stock up on a Thick Jam. Might be easier.

I like the Strawberry Preserves too.

Fig Preserves are great but I think they are " Worstest ",
or Worster, for seeds.
LOU

This works fine. I heated it for a couple of minutes in the microwave and then pushed it through a fine sieve with a wooden spoon. You will lose a bit more than half but so much better without the seeds.

So thankful that I found this! I just bought 7 containers of boysenberry jam (because Knott's berry farm stopped making it), but the brand I found has seeds :( now I don't have to find and buy another lot that is seedless!
