The juniper berry is the blue-black berry of an evergreen bush which is dried and used in cooking with strongly flavoured foods such as game. Famously used in making gin. I have heard it said that, if you eat sufficient junipers, your wine will develop a scent of violets. You are welcome to try to find out how many. If using in cooking, crush them lightly to assist the release of flavours once it is added to the dish.
