What each ingredient does

Vinegar: Extracts the raspberry flavor and adds sharp acidity that gives the finished vinegar its tang.
Fresh raspberries: Provide the main fruit flavor and aroma as they steep in the vinegar.
Raspberry juice: Carries concentrated raspberry flavor and color into the sweetened mixture.
Sugar: Adds sweetness that balances the acidity of the vinegar and gives the syrup body.
