How to Make Sour Juice From Unripe Grapes

Step 1: Prepare Grapes

Cut unripe green grapes from their bunches and wash them thoroughly under running water.

Step 2: Separate Grapes from Stems

Carefully separate all the washed unripe green grapes from their stems.

Step 3: Cook Grapes

Place the separated grapes into a medium pot. Add about 1/2 cup of water to the pot. Cover and cook over low heat until the grapes become soft, approximately 10-15 minutes.

Step 4: Smash Grapes

Once the grapes are soft, use a potato masher to thoroughly smash them in the pot.

Step 5: Add Salt

Add about 1/2 teaspoon of salt to the smashed grapes and mix well.

Step 6: Strain the Juice

Pour the smashed grape mixture into a fine-mesh strainer placed over a clean bowl. Use a spoon to press the pulp against the strainer, extracting as much juice as possible.

Step 7: Extract More Juice

To extract any remaining juice, add about 1/4 cup of additional water to the pulp in the strainer and continue pressing with a spoon.

Step 8: Freeze for Storage

Pour the extracted sour grape juice into small portion molds (like ice cube trays). Freeze the juice until solid to store it for a long time.

Step 9: Store Frozen Juice

Once frozen, remove the individual portions of sour juice from the molds and transfer them to a freezer-safe bag for convenient storage and use as needed.

• Freeze the sour juice in small portions (e.g., ice cube trays) to store it for a long time.

• Use this very sour juice as a substitute for lemon in your cooking or to add tanginess to dishes.
