Common juniper
Its astringent blue-black seeds, commonly known as "Juniper berries", are too bitter to eat raw.  They are usually sold dried and used to flavour meats, sauces, and stuffings. They are generally crushed before use to release their flavour. The berries are used to flavour certain beers and gin. The Slovak national alcoholic beverage Borovička is also flavoured with juniper berry extract.
