When life gives you unripe grapes, make ab ghooreh.
12 pounds unripe grapes
1 tablespoon salt
1 teaspoon citric acid
1/2 teaspoon sodium metabisulfite
Wash the grapes and remove the stems. Drain and pat dry.
Extract the juice by grinding the grapes in a blender, food processor, or juicer. If you use a blender or food processor, pass the pulp through a fine or medium-fine sieve. I don’t mind if the juice has some pulp.
Pour into a non-reactive pan, add the salt, and bring to a boil, stirring often. Cook only one minute and remove from the heat.
Add the citric acid and sodium metabisulfite, if you are using them. Stir well to mix everything in.
Pour into sterilized bottles. Seal the bottles (boiling in a water bath, if you like.) Keep in a cool and dark place.
