Preparation

Alternate in a jar a row of blueberries, a row of sugar. Cover the jar and put it in a hole made in the ground. The pit is covered with straw. Leave for about 3 weeks. After 3 weeks, put on double refined alcohol (which results from the first round when the traditional brandy is boiled in a distillery, and it is 55° proof). Alcohol is added according to the desired strength.
