Is Frying an egg exothermic or endothermic reaction?

The egg requires heat to be cooked. This means that in order to start the frying "reaction", a certain number of joules of heat have to be added to the frying pan, which transfers the heat to the egg. The egg solidifies as a result of the frying reaction.

If frying the egg was exothermic, the egg would produceheat when fried (which would be very strange!).
