It looks a bit congealed, which i find happens with nonstick surfaces...is the pan non stick?
I have moved up to using stainless steel saucepans with the lid on to keep the moisture and cooking on full heat stirring now and again.
I find this stop the viscosity and keeps the base more fluid like...which i find is more like a madras.
Id be interested to know if its a nonstick pan?
