Actually, there is food grade lye. It is used to process olives and to give a nice shine on bagels & pretzels, among other food uses.
I buy mine 40 lb at a time from Boyer Corporation. Even with shipping the lye is less than $2.50/lb
Check the plumbing section of your big box store (Lowes, Home Depot, etc). Make sure the container says 100% sodium hydroxide (or 100% lye).
