Grape Marmalade

This is grape marmalade the way folks made it before pectin came in a box. Two ingredients, grapes and sugar, plus a little patience do all the work.

The method is the old slip-skin trick. You squeeze the skins off the grapes and set them aside, simmer the pulp until it’s soft enough to push the seeds out, then reunite the seedless pulp with those reserved skins. Concord-style grapes shine here because the skins carry both deep color and the natural pectin that helps the marmalade set without any store-bought help.

Sugar goes in at two-thirds the volume of the combined fruit, so it stays fruit-forward rather than candy-sweet.

Then it’s a slow simmer, stirring often so the bottom doesn’t catch, until the juice sheets off a spoon in a single sliding curtain instead of separate drips. That sheeting is your signal it’s ready to jar.

Kitchen Tips

• Use slip-skin grapes like Concord for the most pectin and boldest flavor; truly seedless grapes set softer.
• Cook the pulp just until the seeds release, then sieve them out before the skins go back in.
• Test the set by chilling a spoonful on a cold plate; if it wrinkles when you nudge it, it’s done.

Variations

• Add a strip of lemon peel or a squeeze of juice for brightness and a firmer set.
• Stir in a pinch of cinnamon or a splash of port for a spiced holiday version.
