Tools: Use a small nonstick skillet with sloped sides, and a plastic spatula with a fine edge. These make it easier to fold the omelette.
Heat: Turn the heat on so the skillet will be hot before you add the eggs. It should be hot enough that the egg mixture sizzles and starts to cook immediately, but not so hot that the egg layer promptly forms a huge bubble in the middle. On my stove, pointing the dial marker at “Low” is ideal.
Lubricant: Use about a tablespoon of ghee, also known as clarified butter, available in ethnic or international stores. It is better for you, and MUCH more heat-tolerant than ordinary butter or margarine, so it won’t burn. Ghee is a crucial ingredient in a perfect omelette – nothing else performs as well.
Eggs: In a small bowl, scramble together 1-3 eggs. Most people like a 2-egg omelette; vary according to appetite. Farm-fresh or organic eggs tend to have better color, texture, flavor, and nutrients than ordinary commercial eggs.
Milk: Add 1-3 teaspoons of milk. It makes the eggs blend better and improves flavor. Skim or other lite milk will save calories; whole milk, half-and-half, or cream make for a heavier and richer omelette. I typically use half-and-half, sparingly. Once the eggs are scrambled, mix in the milk. Pour the egg mixture into the skillet. If it doesn’t spread evenly, tilt the skillet gently to fill out the circle.
Spices: Salt and pepper to taste. White pepper doesn’t make dark flecks in the eggs, if you care about that. Sage, oregano, sweet marjoram, thyme, cilantro, or parsley are also good. Add just a pinch or a spinkle of spices to the top of the egg circle.
Cheese: Any kind of cheese that melts easily will work in an omelette. Swiss, cheddar, and mozzarella are excellent. Flavored herbal cheeses are also nice. Use 1-2 singles or about 1/8 cup of shredded cheese. If you’re carving cheese off a block, make thin slices or shavings so they’ll melt. If you want chunks of cheese, cut thicker slices from a block and dice them before starting the eggs. Add the cheese when the egg layer is mostly cooked but still wet on top.
Filling: Many types of vegetables (cooked or raw) and meat work in an omelette. Peppers, onions, mushrooms, and tomatoes are good vegetables. Chicken, turkey, sausage bits, bacon bits, beef chips, diced ham, etc. are good meats. (This is a great way to use leftovers.) Slice, dice, or chop them – and heat them if they were cold -- before starting the eggs. Store filling ingredients in small bowls within reach of the skillet. Add about 1/8 to 1/4 cup of filling when the egg layer is cooked and the cheese is melting. Spread filling from the middle of the egg circle towards one edge.
Folding: With the spatula, carefully lift the empty edge of the egg circle. The underside should be light brown. Fold over the filling, press gently, and hold for a few seconds to allow the filling and cheese to meld. Turn the heat OFF. Let the omelette sit for about a minute. Check the underside; it should be a slightly deeper brown. Hold a plate close to the skillet, slide the spatula all the way under the omelette, and quickly transfer the omelette to the plate.
