Place in a bread machine in this order:
290 ml water
1 T sugar
1 t salt
(2 T milk powder)
1½ T olive oil or butter
450 gm flour (bread flour or all-purpose flour)
Make a small well in the ingredients and pour in:
2 t yeast
Turn on dough cycle. When done, heat pizza stone under the grill in your oven. (Or you can cook it in a frying pan on the stove with a lid, but it doesn't turn out quite as nicely as when done in the oven.)
Using a handful of dough for each naan, press and spread on a lightly floured surface until it is your desired shape, less than 1 cm thick.
Dust pizza stone with a little coarse flour (like whole wheat, graham, or corn meal - whatever you have), and place one or two pieces of naan on it. If your naan is has flour on it from being rolled out, that step may not be necessary. The point is, you don't want it to stick to the pizza stone. Grill for 4-5 minutes, until nicely browned on top.
