beaten egg yolks
Egg yolks are rich in choline, selenium, and lutein, while providing high-quality lipids and fat-soluble vitamins including vitamins A, D, and E. A single large yolk contains approximately 5 grams of fat and 2.7 grams of protein.
About
Beaten egg yolks are the separated and mechanically whipped yolks of chicken eggs, a prepared ingredient rather than a raw component. Egg yolks consist primarily of lipoproteins, lecithin, and water, with a rich, golden-yellow color derived from carotenoid pigments. When beaten, the yolks incorporate air, increasing volume and creating a lighter, mousse-like consistency that ranges from pale to ribbon-like in texture depending on beating duration. The emulsifying properties of egg yolk lecithin make beaten yolks particularly valuable for stabilizing sauces, custards, and baked goods.
Culinary Uses
Beaten egg yolks serve as a foundational technique in classical and modern cuisine, functioning as an emulsifier, thickener, and leavening agent. They are essential in creating hollandaise and béarnaise sauces, custard-based desserts (crème brûlée, zabaglione), and mousse preparations. In baking, beaten yolks aerate cakes, sponges, and soufflés, contributing richness and structure. They also bind ingredients in mayonnaise, aioli, and pastry creams. The technique of beating egg yolks with sugar until pale and voluminous is fundamental to many French and European pastry preparations.
