From "To Set Before a Queen"--a cookbook written by a former cook for Princess Elizabeth's household (Queen Elizabeth before she was crowned, that is). It's an interesting cookbook, with some good recipes and some interesting anecdotes. She claims that the royal family were all "addicted" to this recipe. She also says that this is the recipe she was given to use at Clarence House. I've tried it and like it quite well myself. Posting here as it's an older cookbook and I don't want to lose the recipe. Since the rinds are used, it's best if you can find organic fruits without oils or waxes or chemicals on the rinds. Failing that, be sure to clean them very well--I soak them in vinegar water, then rinse them under very hot water. I can't recall the amount you get at the end, so I am estimating. Times don't include cooling time.
