Cut the pine cones (put on plastic gloves) into fine slices with a sharp knife.
Fill the Swiss stone pine slices in layers with the rock candy in a glass and pour the grain over them. Cover the jar with foil and place it in a sunny window. Let it rest for 14 days.
Then strain through a cloth and bottle. Depending on the maturity of the pine trees, the pine schnapps turns from light pink to dark brown.
