The Webster-Merriam Dictionary defines feast as “something that gives unusual or abundant enjoyment." Here we mean for it to encompass all facets of our daily experience, from eating, to working, to sitting on the porch. So with that, you are invited to join our cyber-table. We hope you enjoy the feast!

Eggs, Part IV

     Eggs are a complex little entity with a versatility unmatched by any other ingredient. Their yolks are used as emulsifying or thickening agents, as in mayonnaise and dressings, Hollandaise sauce and all kinds of desserts, from a traditional Italian zabaglione to a classic French crème brulee. Their whites are utilized especially for the fluffy, airiness they possess when beaten, as in meringue and Swiss buttercream frosting. When combined, its safe to say that the possibilities for egg usage are innumerable (or at least, not worth spending your life trying to count).
     Humans like to eat the eggs of other species. But most kinds of eggs aren't easily accessible from a regular grocery store or Farmer's Market and are seen as delicacies, like quail and duck eggs, caviar and roe. So we stick to the eggs from our beloved friend, the hen.

Figure 1A.
     A chicken egg is made up of many small parts. (see Figure 1A.) The outer shell is slightly porous, and made primarily of calcium carbonate (CaCO3), the main component in pearls and sea shells (evolution, anyone?). The eggshell also has an outer and inner protective lining, like a little eggy sleeping bag. Aww. Eggs come in many shapes and sizes—and even colors! The color varies depending on the breed of the animal, and can range from brown to pink, white, yellow, green, and blue! (see Figure 1B.)
     The white part of the egg is called the albumen, and there are technically a couple of layers of this even though it looks like one clear mass. The albumen is almost all protein (with some trace minerals) and is made up of about 90% water.
     The pretty yellowish-orange part of the egg is the yolk, aka. vitellus. The vitellus contains fat, cholesterol, vitamins and minerals, protein and lecithin (an emulsifier).

     Beyond these commonly known parts of the egg, there also exists the chalazae cords, clear-whitish strands connecting from the inner lining of the shell to the outer lining of the yolk and acting as elastic-like bands that keep the yolk centered comfortably within the egg. There are a few other thin linings and layers around the yolk, and also, of course, the nucleus where the little DNA message from the chicken is stored.
     I think the recipes that do eggs the most justice and really highlight their special diverse gifts are the recipes that use different parts of the egg throughout different parts of the recipe, like in soufflé, Eggs Benedict and Lemon Meringue Pie. Another favorite is the enamored Italian Timpano, a dish fit for kings, containing hard-boiled eggs, raw, beaten eggs, and eggs in its dough, all wrapped up like a drum. (see Figures 2A. and 2B.
