Rachel, from The Essential Rhubarb Pie! Yup, Rachel has won a copy of The Blackberry Farm Cookbook with her answer to the question, "What is your favorite fruit or vegetable?" Her answer, WATERMELON, was randomly chosen using RANDOM.ORG.
Other answers included (multiple entries of) apples, blueberries, butternut squash, carrots, cherries, oranges, peaches, strawberries, watermelon plus rhubarb, rutabaga and cherimoya(!).
Congratulations, Rachel! Good choice. I'll be in touch.
