On a regular basis, I make a lemonade syrup that requires me to "zest" dozens of lemons. I have found the citrus zesters commercially marketed to be useless for such a large scale job, and vegetable peelers to be marginal at best, causing blisters, cutting to deep even with light pressure, and never sharp enough. I used a "harp" peeler for about 3 batches of 4 doz lemons, but then the blade kept popping out, and then the harp cracked. I have spent so much money trying to find a decent sharp peeler. I've tried all the major retail brands and everything available from Walmart to Target to the outlet kitchen stores in my area. HELP! I am making a batch of syrup as we speak, developing a blister on the base of my index finger using the best peeler I have found ... from the Dollar Tree! How sick is that?
