	Why do popadoms curl? When you fry popadoms, why does it curl upwards away from the layer of oil? Jo via email
	Possibly because the top of it's exposed to the air, so you get more evaporation off the top. The bottom's going to fill with oil, the top's going to dry out, so the top's going to get smaller and it's going to curve upwards.
