Do you have to use water to steam the ribs? Could I use beer?
Great idea. I'll try beer too next time. Let us know how it goes!
Just be sure to check it a little early to make sure you're not close to burning off all the liquid -- maybe even splash a little extra in the bottom of the pan to start.
Are the ribs steamed or boiled in the pan with the water / beer?
They're steamed -- there's only a half cup of liquid in each pan and the meaty side of the ribs is curved up, not resting in the liquid.
