These make lovely gifts, and the size can be varied (I've made 1/2 pint and pint jars with equal success.) These will keep in the cupboard for up to one year (theoretically!) Depending on the size on your jars, you can either bake them in muffin tins, or use crumpled aluminum foil on a baking sheet to keep them from sliding.
Correction: Thanks to the review, I'm redacting the "storing in cupboard" portion of the note. These should be stored in the freezer or consumed immediately.
