A whisk is one of those versatile kitchen tools that everyone seems to have in their first apartment, even if they don't actually cook (along with that weird spaghetti spoon with the hole in it).

Whisk until eggs are fully combined; add salt and pepper to taste. Pour your eggs into the pan once its butter starts to gently bubble and vigorously whisk/stir the eggs with your whisk/spoon.

Beat for 2 minutes using an electric hand whisk. Spoon into the prepared tins and level the surfaces. Bake for 25-30 minutes, until well risen and coming away from the sides of the tins.
