3⁄4 oz Nocino (Or any other similar walnut liqueur)
3⁄4 oz Lemon juice
1⁄2 oz Maple syrup (I used the real stuff from Canada. Try to find a thinner, high-quality syrup.)
1 pn Salt
Shake everything vigorously over ice, then pour it straight up and serve.
Depending on your sweetness tolerance, you may want to reduce the syrup to 1/3 or even 1/4 ounce.
