I was experimenting on dough for chapathi, which is basically wheat tortilla. This is how I normally prepare it,
Mix whole wheat flour and salt with room tap water, often 20 to 30 degree Celsius .
Knead with oil until I get a consistent dough.
Immediately press with a rolling pin and cook in a pan
In this method, the product is often crisp, never fluffy and no particular taste.
But today I experimented with hot boiling water as I read recently it denatures protein in food, which prompted me to experiment.
When I cooked my chapathi, those were extra tender but more importantly, it was very sweet, even though I added salt .
I hope to find a scientific explanation to this phenomenon.
