"One of the most refreshing drinks for the summer is an Elderflower Cordial. An Elderflower Cordial Recipe is quick and easy to make and a great excuse for a long walk collecting flowers. The Elderflower season is short, late May to the latest, mid-July, if you live in the the north or Scotland. The heavily scented flowers make a wonderful, refreshing Elderflower Cordial which when stored in sterilised bottles will keep for months. If you are out collecting Elderflowers, a word of warning make sure you have permission to pick them and never pick flowers from trees on roadsides, they may be tainted with petrol fumes...."
