Asparagus might be available year-round, but early summer is the ideal season to enjoy this nutritious bud-tipped vegetable. Head to your local grocery store or farmer’s market to find verdant spears in a range of colours and stalk sizes; ultra-thin pencil asparagus works well in raw salads and light pasta dishes while green, purple, and white heirloom asparagus varieties are thick enough for grilling or roasting at high temperatures.
