Lye bath sourdough bagels

I finally got around to purchasing a container of food grade lye . I had tried to find info on lye baths for bagels but there is very little out there and the percent of lye to water that was used seemed way off. I am glad that I pursued this and have some data that I hope will help others. I purchased the lye on Amazon here . Will likely last me a good long while. I used 5 grams in 1 gallon of filtered tap water. This is approx. 12-12.5 % alkalinity.
