Well that was a brilliant read Commis - thanks.
An important part I took from it is as follows:
"Since paprika contains significant amounts of sugar, it must not be overheated, as the sugar will quickly turn bitter. Frying paprika powder in hot oil is therefore a critical procedure that must last no longer than a couple of seconds"
I will never add Paprika to my spices and fry with Onion and G&G again.
Cheers
