The Greek Citron lemon is a spectacle to look at. They are large and tapered to a point at one end. When unripened, they're a light green color — combined with its shape, the Greek Citron looks almost avocado-like until it ripens. We primarily see Greek Citrons prepared as candies to eat alongside your coffee or baked into fruit cakes for a fun and bright yet chewy bite (via Olive Tomato).
