The No. 1 rule of edible flowers is knowing how to identify them. Pick edible flowers on a dry, sunny day. Most flowers should be picked when they have fully bloomed and are not yet starting to wilt. Rinse the flowers quickly under cold water or swirl them in a large bowl of cold water to remove dirt and tiny insects. Then, gently shake off the water but not so vigorously that you remove the pollen, which often has a lot of flavor. If you plan to dry your flowers, place them on paper towels or clean tea towels in a single layer. Let them dry in a warm, well-ventilated place, turning them over once or twice a day. Depending on the thickness and moisture content of the flowers, this can take several days. You can also dry flowers in a dehydrator. Follow the gadget instructions, and, just like with air-drying, make sure not to overlap them. Here are 20 edible flowers to grow in your garden.
