Grape Jelly
Ingredients
Directions
Extract the juice
Place grapes in a stone crock in a kettle of boiling water.
Gently stir the grapes from the bottom with a wooden spoon until all are broken.
Tie a towel over the mouth of an empty crock and place a quart of hot grapes on it.
Occasionally pass the spoon under the grapes to remove the pulp, but do not press them.
Drain another quart of grapes and repeat until all are drained.
Measure the juice and add 1 pound of sugar for every pint.
Make the jelly
Heat the juice over the fire until it boils, then add the sugar and dissolve completely.
Keep the mixture very hot but do not allow it to boil.
Pour the jelly into glasses and cover when cold.

What each ingredient does
- Grapes
- Provide the juice and natural pectin that gives the jelly its body and set.
- Sugar
- Sweetens the juice and helps it set into a firm, spreadable jelly.
The step that matters
Keep the mixture very hot but do not allow it to boil. Once sugar is dissolved, boiling further can break down pectin and weaken the set, while holding it hot keeps it fluid enough to pour. Gentle heat preserves the gel-forming structure.
