Rugosa roses are known for producing large orange and red hips (that’s the fruit that contains the seeds) in the fall. The hips are rich in vitamin C and can be made into a liqueur. In fact, Koval Distillery in Chicago sells a rose hip liqueur.
Make your own by harvesting fresh rose hips and cutting the woody ends off, then soaking in vodka for two or three months. Strain the vodka and mix with simple syrup (equal parts sugar and water, heated until the sugar melts and then allowed to cool) until it’s as sweet as you’d like it to be. Then let it sit for another couple of weeks, and it’s ready to drink.
