Grape Marmalade

Method

Pick over, wash, drain, and remove stems from grapes. Separate pulp from skins. Put pulp in preserving kettle. Heat to boiling-point, and cook slowly until seeds separate from pulp; then rub through a hair sieve. Return to kettle with skins, add an equal measure of sugar, and cook slowly thirty minutes, occasionally stirring to prevent burning. Put in a stone jar or tumblers.
