It wets the dough for getting it to just stick, while adding less water. I think it's 50/50 water and vodka, for ~25% net water reduction.
I'm also want to try))The ribs turned out fantastic btw.
A word of advice. Don't add sweet potatoes to a crock pot stew.
The flavor is okay, but they disintegrate into mush and just vanish. But we have to experiment with recipes, learning as we go on. This one was a dud that I won't repeat.
I have had success with wrapping chunks of sweet potato in foil and setting the packet on top of the stew. They cook through but don't disintegrate, then I stir them in at serving time.
Made chicken cordon bleu last night. Came out decent. Next time, I'll pound the cutlets to thin them and make for easier rolling. I'll also do deli-thin ham, and use a little more cheese.
