Grape Juice
Ingredients
Directions
Prepare the grapes
Pick over and wash the grapes, preferably Concords.
Place grapes in a porcelain kettle with just enough water to prevent sticking.
When the skins crack, remove from heat.
Extract and sweeten the juice
Pour the contents into a flannel bag, pressing out the juice.
Add nearly half as much sugar as juice.
Return the mixture to the kettle. Dissolve the sugar.
Bring the juice to a boil.
Can and store
Pour the juice into pint cans.
Seal the cans.
When opened, dilute with water to taste.
Store in a cool place.

What each ingredient does
- Fresh blue grapes
- Provide the juice, along with natural sugars and flavour, once their skins are cracked by heat.
- Sugar
- Adds sweetness and balances the tartness of the grape juice.
The step that matters
Bringing the juice to a boil after adding sugar. Sugar must dissolve fully before boiling so it does not scorch on the bottom of the kettle. Boiling then heats the juice enough to help preserve it in sealed cans.
