For whatever reason I can't think of strawberries without thinking of that song. Have you been to a farmers market yet and tasted the delisousness of strawberries in season? Oh! And did you know, strawberry jam is SO easy to make. As with most of my hobbies, I was inspired by Tracy to try making jam, but did not have a steamer pot thing to help seal the lids. My mom said (and it DID work) that after you put the jam in the jars, screw on the lids, you can turn them upside down and they will seal themselves. Test the lids by pushing down on them and if they don't pop back up - they're sealed. If they do pop back up, put them in the freezer. You now have freezer jam. The recipe for jam will be on the pectin box that you buy. Beware: Strawberry jam has MORE sugar in it than it does strawberries. But. I'm ok with that.
I made jam for the moms for Mother's Day. I got the cute tutorial for the cover from here. It's all hand sewing, and takes a bit of time to do. I LOVE how cute they look, but am torn on whether the time is worth it for something that just gets thrown out. Know what I mean?
Strawberry jam is a nice idea for teachers gifts though (is it too late for that?), and you could just put cute fabric under the lid. And inexpensive. I figured about $1.50/8 oz. jar.
