The very funny Sidewalk Egg Frying Day is celebrated on July 04. 2017. It is an annually celebration of the summer and the sun. In the summertime it often gets so hot, especially the sidewalks exposed directly to the sun, that you could fry an egg on it. Sidewalk Egg Frying Day is the perfect opportunity to try it yourself. Frying is a method of dry cooking over high heat. Herbay causes the Maillard reaction compounds on the surface, which are responsible for the typical color and taste of fried food. If you're close to London, you could also use the famous Walkie Talkie Tower to get your eggs done.
