I heated up the electric griddle to between 325-350 degrees. You don't want it too hot or the biscuits will burn. (I learned that with my first batch.) I spooned biscuit batter onto the griddle just like you do for drop biscuits on a baking sheet. (You could go to the work of rolling the dough out and using a biscuit cutter to give you perfectly round shapes, but I didn't want to deal with the added mess since I was baking in a makeshift kitchen in the basement.) Allow them to cook for 8-10 minutes before flipping to allow the bottoms to brown nicely. Flip over and mash slightly with the back of the spatula to make then all about an even thickness. Allow to cook anther 8-10 minutes to brown the other side and to allow the centers to be done.
We served them up with sausage gravy cooked on a hotplate. Delicious!
