The perfect biscuit is delicate, flakey, and fluffy all thanks to the interplay of fat and flour. Unfortunately, this flakey, buttery outcome faces a lot of obstacles. If you've ever attempted to make a batch of biscuits, you're likely familiar with how finicky the process is. If the proportion of flour and fat is even slightly off, the consistency of your biscuits will miss the mark; too much flour results in dry, crumbly biscuits, while uneven fat distribution or overworked dough results in tough or dense biscuits. While there are plenty of tips to achieve the desired fluffy, melt-in-your-mouth crumb, adding a hard-boiled egg yolk to the dough is probably one you haven't tried.
Boiled egg yolk is essentially an extra dose of pure fat that's also been rid of its water content that'll easily disintegrate and distribute throughout the flour to create a buffer against gluten formation. Gluten is the compound made by the reaction of two key proteins in wheat flour that gives boule bread and pizza dough its chewiness. With biscuits, however, the goal is to avoid this chewiness. So, by adding hard-boiled egg yolk to a biscuit recipe, you'll thwart the formation of gluten, thereby resulting in a buttery, flakey crumb that'll dissolve in your mouth. The hard-boiled egg yolk hack is actually a longstanding practice for other pastries like shortbread cookies, shortcakes, and scones that also possess the same crumbly, buttery, and tender nature.
How To Incorporate Hard-Boiled Egg Yolk Into Biscuit Dough
Adding hard-boiled egg yolk to biscuit dough doesn't require any ingredient swaps or proportion changes. You can thus add them to your favorite biscuit recipe as a supplemental ingredient. For a standard batch of biscuits, you can use one or two hard-boiled egg yolks. You'll want to make sure you hard boil your eggs, as runny or jammy eggs aren't ideal for distribution in the flour.

You can use hard-boiled egg yolks fresh out of the pot or you can wait for them to cool completely. To add them to the batter, you'll run them through a mesh sieve or grate them along with cold butter into a bowl or mixer with the rest of your ingredients. Of course, all the same tips for a flakey crumb still apply, like using frozen, grated butter, and barely working the ingredients with your hands or a fork to form loose and crumbly dough.
Similar to other yolk-heavy types of bread like brioche or challah, the addition of egg yolks to your biscuit dough may give your biscuits a yellow hue. Once you taste the buttery, perfectly executed crumb, yellow coloring will be a welcome visual cue.
As it turns out, adding hard-boiled egg yolks to your biscuit dough is a way to ward off an overworked, tough dough that can be the downfall of a butter-based pastry. When the trick is employed, the pastry shatters and then dissolves in your mouth quickly, tasting like a knob of flaky butter.

Eggs function as natural emulsifiers, combining liquids and fats to achieve a smoother dough texture. Additionally, eggs also play a role in strengthening the gluten network to enable the bread to maintain a good shape and volume. Eggs contribute to prolonging the shelf life of bread by reducing water activity.
Eggs play an important role in everything from cakes and cookies to meringues and pastry cream — they create structure and stability within a batter, they help thicken and emulsify sauces and custards, they add moisture to cakes and other baked goods, and can even act as glue or glaze.
According to our friends at Delish, adding a teaspoon of baking soda to your boiling pot of water will help the shell peel off seamlessly. Why? The alkaline in the baking soda will help your egg whites loosen up from the shell, making it easier to peel.
Whole eggs, egg yolks and egg whites are all used to add structure to batters. The yolk's elevated fat content helps it bind fats and liquids together through what's called an emulsion. Emulsion is just a fancy word for two liquids that don't usually blend together on their own, like oil and water.
While biscuits receive some leavening power from chemical sources — baking powder and baking soda — the difference between serviceable and greatness comes from the extra rise that steam provides.
Customer appeal: Eggs enhance the appearance of products through their colour and flavour, and they improve texture and grain. Structure: Eggs bind with other ingredients, primarily flour, creating the supporting structure for other ingredients.
Eggs are natural binders, helping hold all other baking ingredients together and increasing the viscosity of batters and doughs. Egg white has the capability to gel and is frequently used as a binding agent in many different prepared foods.
But besides the nutritional benefits there are a few other good reasons to use egg in breadmaking. It makes the bread lighter and fluffier. The reason for that is the fat in the yolk that inhibits gluten formation just as any other fat would. This results in a looser dough that can expand and puff up more.
If there isn't enough egg, your batter or dough may not be able to hold its structure or could end up overly dry or dense. On the other hand, if there is too much egg, your baked goods could lose their shape due to excess liquid, or have a rubbery (or even overly cakey) texture depending on the recipe.
The vinegar in the water makes the eggs easier to peel. Here's why: The vinegar's acid not only dissolves some of the calcium carbonate in the shell, it also helps the whites set faster. Running the hard-boiled eggs under cold running water as you're peeling, meanwhile, helps the shell separate from the membrane.
Eggs are responsible for giving baked goods structure, which means the amount you use directly affects the resulting texture. Using too few eggs will make your desserts dense, but using too many will make them rubbery. The explanation for this lies in the fact that eggs are made up of protein.

Eggs exhibit excellent binding properties, meaning they help hold ingredients together. Specifically, egg proteins can react with other ingredients to bind them together via processes of gelation or coagulation. This helps food products to maintain desirable structure, texture and mouthfeel.
To avoid this, try using as little flour as possible while preparing to roll your dough. Dry – “Dry” or “Crumbly” dough is a product of over-mixing or using too much of any ingredient during the mixing process. This can be reversed by adding one to two tablespoons of liquid (water, milk or softened butter) to your mix.
