Summertime is the ultimate time for fruits like oranges and lemons. They are used in many cakes, cookies and stuff like that. I made some really nice Lemon & Rosemary Cookies the other day – you should try them! Delicious and refreshing. This recipe for Polenta Biscuits today is equally delicious and made with mandarin oranges (tangerine) – another citrus fruit I like to use in summer.
