This method is time consuming but learning the process of emulsification is best done by hand before attempting other methods. Controlling the temperature in this method is more challenging but much quicker and is useful when making larger quantities. The butter must be hot enough to partially cook the yolks. If the sauce tastes like raw yolks it will need to be heated in a heatproof bowl over a bain-marie, as above, whilst beating until it is warm enough to partially cook the yolks.
It the butter is too hot the yolks will cook completely and the Hollandaise will be grainy. If the butter is added too quickly the emulsion will break and the sauce will split. This is the method is often used in restaurants and be used with up to 10 yolks. Hollandaise should be made just before serving.
If the sauce gets too hot it will become thick then split as the water content evaporates and the sauce gets too hot. Add a few drops of water occasionally and stir to maintain the correct consistency. It is not advised to keep Hollandaise for more than 1 hour before serving.
The Hollandaise is not thick enough The mixture was not heated enough. Too much liquid has been added. The Hollandaise looks oily The sauce is too hot.
Egg Yolk Emulsions Preparation and Information. All About Rice. Finishing a Cake. Whisking Method. Rubbing-In Method. The proteins in an egg white are globular proteins, which means that the long protein molecule is twisted and folded and curled up into a more or less spherical shape. A variety of weak chemical bonds keep the protein curled up tight as it drifts placidly in the water that surrounds it.
When you apply heat, you agitate those placidly drifting egg-white proteins, bouncing them around. They slam into the surrounding water molecules; they bash into each other. All this bashing about breaks the weak bonds that kept the protein curled up. The egg proteins uncurl and bump into other proteins that have also uncurled. After enough of this bashing and bonding, the solitary egg proteins are solitary no longer.
The water in which the proteins once floated is captured and held in the protein web. If you leave the eggs at a high temperature too long, too many bonds form and the egg white becomes rubbery. Experiment with heating eggs by hard cooking eggs , by making deviled eggs , or by making flan. For example, oil must be added slowly to water so that the lecithin within the egg yolk can thoroughly coat the small droplets. This coating acts as a barrier to prevent the droplets from joining back together flocculating or coalescing to enhance emulsion stability and improve product appearance and texture.
Some common applications for eggs as emulsifier beyond mayonnaise and sauces includes salad dressing, ice cream and baked goods such as muffins, bread, cinnamon rolls and cheesecake 6 to name a few. In ice cream, eggs added during the freezing process help promote a smoother texture and ensure the ice cream does not melt rapidly after serving.
Within the commercial baking industry, which relied upon eggs as the first emulsifier, a proper emulsion impacts both product and process. Eggs can help increase product volume, supply a tender crust and crumb, finer and more uniform cell structure, a bright crumb color and slow the crumb from firming, increasing product shelf life.
In terms of process, emulsification activity enables proper blending of ingredients and protects the dough during mechanical handling. Close Menu. Can you freeze eggs?
