It's still chilly in some parts, but most everyone at this time of year begins to feel the urge for the fresh and new, from spring cleaning to gardening to cooking with the new season's produce. Let's celebrate the return of some old favourites.
Asparagus
Belonging to the lily family, these succulent spears supply great nutrients sure to put a spring in your step: folic acid, potassium, vitamins A,C,B6 andK, riboflavin, thiamine, niacin, phosphorus and iron. They are also high in dietary fibre, protein and asparagine, which helps to break down oxalic and uric acid crystals in kidneys and muscles.
Fresh asparagus tastes best when boiled for only 1-2 minutes. Before any cooking, hold each spear in both hands and bend it until it snaps, where the tender and tough parts meet.
