10 green walnuts chopped

500 ml vodka

300 ml dry French vermouth

½ cup sugar

1 vanilla pod

2 cloves

1 teaspoon sichuan pepper

1 cinammon stick

1 orange, sliced

Put everything into a jar and leave it in the sunlight, shaking it every day and watch as the liquid turns from clear to an alarming green to a dark, dark green.

After a couple of weeks, strain the liquid into a clean bottle and leave in a dark place for 12 to 18 months.
