My son wants lemon bars for his b-day and I've lost the recipe. I've looked and looked and even looked on-line, but can't find it.(Cooks Illustrated has it, but I"m not a member, so I can't get it) It was called perfect lemon bars by Americas test kitchen. Great recipe--if anyone has it, would you please post it or direct me to a site that has it? I thank you and my son will thank you!
