Prepare the ingredients for the ice cream. Berries can be any, I have honeysuckle. Honeysuckle is not a very sweet berry, so the amount of sugar is up to you.
Sour cream can be any fat content, but the fatter, the tastier the ice cream will be. And, of course, do not take sour cream. In a bowl, mix the sour cream, sugar, and purple Basil leaves. Punch with a blender until fluffy.
