Instead of purchasing olive oil in aerosol cans, I have been using an air pump like this one. This gives you the freedom to choose high quality oils instead of being stuck to the brands that put oil in cans and you can do without the propellant that comes in those cans. You do have to pump the bottle a few times before spraying onto a surface but it’s minimal effort for low-oil meal preparation. The total amount of oil misted onto a pan probably measures less than a quarter teaspoon.
Make sure the pump you purchase isn’t clear like to minimize rancidity caused by light.
