The main ingredient in a traditional French omelette is eggs. Eggs are whisked together and cooked gently in a pan until set, but typically kept soft and often slightly runny in the center. The preparation method highlights the quality of the eggs, emphasizing their flavor and texture. While variations exist, a traditional French omelette is usually folded into a classic oval shape and may include simple fillings like herbs, cheese, or vegetables. The emphasis is on the technique used to create a silky, tender omelette that showcases the eggs' freshness.
