Makvali is a traditional blackberry sauce originating from Georgia. It's usually made with a combination of blackberries, minced hot peppers, chopped garlic, coriander, dill, salt, and either unripe sour grapes or lemon juice. The blackberries are forced through a sieve into a bowl, while the hot peppers, garlic, and salt are mashed into a paste and mixed with the blackberries.
