A "grease spray" is a vegetable-based food spray designed to grease molds, baking trays or supports before pouring in a preparation, to ensure easy release from the mold.
It replaces butter or flour for greasing, and is sprayed directly onto the surface to be treated, creating a uniform film that prevents the preparation from sticking.
This ensures rapid demolding, protects molds from corrosion, and makes them easier to clean.
They are generally composed of neutral vegetable oil (rapeseed, soybean, coconut...), sometimes emulsifiers (lecithin), and a propellant gas (nitrogen, butane, propane, depending on the brand).
These sprays transmit neither taste nor odor to the pastry, and are compatible with all types of molds (glass, silicone, metal, etc.).
It's as simple as spraying an even film on the bottom and edges of the mold...
... it takes just a few seconds, turns into a thin layer of white foam, and that's it!
Then all you have to do is pour in the paste.
