Production steps: put the black tea bag and mashed mint leaves into a heat-resistant container, add boiling water and stew for 10 minute. Take out the tea bag, filter out the mint leaves, then add sugar to the black tea and stir until it dissolves. Beat the blackberry into mud with a blender, and then press it on the filter to get the juice.
Pour the juice into the cooled black tea, stir and taste. If it is not sweet enough, you can add sugar appropriately and then put it in the refrigerator for refrigeration. Garnish with ice cubes, fresh mint leaves and blackberry before drinking. Every season has its own flavor, such as summer, which is the flavor of sweet and juicy fruits and refreshing mint leaves, and a little floral fragrance.
