Creamy soy sauce

A delicious touch that will leave your guests wanting more: Place 1 cup of soy sauce in a pot and add 2 teaspoons of cornstarch, stir until thickened. 

If you want a really different burger, play with the types of buns: You can use beet or onion buns. 

Another infallible tip is to caramelize the onion: For that you must place 1 tablespoon of butter in a pan, and add an onion cut into julienne … when the onion is soft, add 1 cup of brown sugar, let it melt until it becomes caramel, and remove before it becomes too brown.
