What can replace milk in crepes? I want to make crepes, but I am out of milk.  Can I still make crepes?  What can replace milk in this application?

I do have yogurt, beer, eggs, cream, butter, flour, salt, and sugar.
Try watered down cream, as you'll still get some of the milkfat, but you don't want quite as much.

Water would probably also work for your crepes, although it would change the taste.
