In a microwave-safe jar (or bowl), crack the egg and mix with the milk and oil. Add the salt, cornstarch, cheese, and baking powder. Mix everything very well until you have a smooth batter.
Microwave it for 2 to 3 minutes on high. If you prefer to use the oven, pour the mixture into small molds and bake for about 15 minutes at 180°C (350°F). The aroma that fills the kitchen is simply irresistible.
Here at home, when I make it, it barely comes out of the microwave before everyone's already digging in with a spoon. And there's not always enough left for a second jar!
