Hi Jerry,
It won't rise as such but rather the air will develope in the mix. Mine usually prove for an hour or two even. If you are seeing two or three small bubbles appearing in the dough it's right enough. I used my recipe again less 1 egg and it was fine. I think the maybe your technique might be what is giving you problems. What are you cooking the naans on? Tava, griddle? Are you absolutely sure it is hot enough? It needs to be smoking hot. Am I right in saying you are using electric to cook still? If you are using electric try using an ordinary non stick frying pan the thinnest metal one you've got. Let it heat up on the hob for a good 5 minutes. Roll out just a little of the dough and drop it in. Brush the top immediately with oil. Flip after 2 or 3 minutes. If it bubbles up after a minute or so in your pan you've found the problem. When you make up the liquid add you Baking powder and salt to the liquid to ensure an even distribution through the mix. Lastly make it sticky. My last dough I mixed entirely with a spoon. It is really just like a thick batter. Don't worry about getting it out of the basin. oily hands and flour in another bowl will make it more managable when you come to use it. The stickier the dough the more air their will be in their. I think BIR's get away with a thicker dough because they have the heat of the tandoor to fall back on. Show us some pics, even if it fails, maybe we can help you better by seeing what you are doing. We will not let you go without Naan ;D ;D ;D ;D Sorry forgot to mention. I have stopped using oil with no adverse effects. Still use the yoghurt though
