In culinary school I discovered two secrets to success with omelets. The first, of course, is butter. The second secret to omelet perfection is a silicone spatula.
If you haven't tried a silicone spatula yet, it's time. These flexible rubber spatulas are a versitile kitchen tool - not only do they spotlessly scrape a bowl clean of cake batter and gingerly fold egg whites into a mousse, but because most are temperature resistant up to 600°, they also coax omelets from hot pans, and other delicate, high-heat jobs.
It may be a kitchen tool you've lived without, but once you start using one, you'll wonder why you denied yourself the pleasure for so long.
