Finally made a batch of pretzels yesterday. Used the recipe at
this link, and did not deviate from it.
In hindsight I should have used about 50% more sodium hydroxide, and less butter. There's always next time.
Do not attempt this recipe unless you are familiar with the dangers of handling sodium hydroxide. Wear gloves and eye protection from the moment you grab the jar of hydroxide pellets until after you neutralize the solution you made with it. If it gets on your skin, just wash it off. If it gets into your eyes, mouth, nose... you're in for a world of hurt - and in the case of your eyes: permanent damage.
Make sure what you use is food/reagent grade. Drain-O will likely produce less than stellar results. And kill you.
I implore you to research and be prepared.
Here they are before the lye dip:
Here they are out of the oven:
I only salted the ones on the right, and they might look ugly, but the taste was nearly spot on.
Enjoy!
