Once the strawberry puree has been strained into the bowl, add 2 cups heavy cream, 1/2 cup sweetened condensed milk, 3/4 cup granulated sugar, 2 teaspoons salt, and 1 tablespoon red wine vinegar and whisk together until the sugar has dissolved. Once the mixture is smooth, taste your ice cream batter — if it needs more sugar, add a pinch, if it's too sweet, add a splash of red wine vinegar.
