With a bit of creativity and understanding of their function in cooking, you can harness the full culinary potential of egg yolks.

Understanding Egg Yolks

Egg yolks are a powerhouse of nutrition and a versatile ingredient in your kitchen. They offer rich flavor, act as a binder, and can emulsify and thicken sauces.

Composition and Nutritional Profile

Egg yolks are primarily composed of water, protein, and fat.

The nutrient breakdown of an average egg yolk is as follows:

Water: About 50%
Protein: Around 16 grams per 100 grams of yolk
Fats: Approximately 27 grams per 100 grams, including both saturated and unsaturated fats
Cholesterol: High in yolks, important for the body’s cellular functions but should be consumed in moderation
Vitamins and Minerals: Rich in vitamins A, D, E, K, B12, and folate, as well as minerals such as iron and phosphorus

The high fat and lecithin content in yolks makes them an effective emulsifying agent in recipes.

The Role of Egg Yolks in Cooking

In cooking, egg yolks serve several key functions:

Emulsifying: Yolks can help blend water and oil-based liquids to create smooth emulsions like mayonnaise or hollandaise sauce.
Thickening Sauces: When egg yolks are heated, they coagulate, allowing for the thickening of custards, sauces, and soups. To prevent curdling, temper the yolks by gradually adding hot liquid before incorporating them back into the main dish.
Adding Flavor and Color: Yolks enrich foods with a distinct taste and impart a yellow or golden color to dishes such as pastries and pastas.
Binding Ingredients: Their protein content helps to bind ingredients together in dishes such as meatloaves or croquettes.

Using egg yolks effectively can enhance the texture, taste, and visual appeal of your food while adding nutritional value.

Storage and Preservation

Storing leftover egg yolks correctly extends their shelf life and preserves their quality for cooking.

It’s essential to maintain the freshness of the yolks using the appropriate methods for refrigeration and freezing.

Refrigeration Methods

When storing egg yolks in the refrigerator, you should keep them in an airtight container. This helps prevent the yolks from absorbing odors from other foods and from drying out. Here’s how:

Place your leftover yolks in the container.
Add a small amount of cold water or a few drops of lemon juice for each yolk. This liquid prevents the surface from hardening.
Seal the container tightly and position it in the coolest part of your fridge, typically at the back, away from the door.

Stored this way, egg yolks can remain fresh in your refrigerator for 2-5 days.

Freezing Techniques

Freezing egg yolks can keep them usable for a longer term. To freeze egg yolks:

Beat the yolks to unify the content as they can become gelatinous when frozen.
If desired, mix in 1/8 teaspoon of salt or 1 1/2 teaspoons of sugar or corn syrup per 1/4 cup of egg yolks (approximately 4 yolks). Label the container with the date and whether you’ve added salt (for savory dishes) or sugar (for baking).
Pour the beaten yolks into an ice cube tray or small freezer containers for portioning.
Once the yolks are frozen, transfer them to a freezer bag or airtight container to save space and prevent freezer burn.

Frozen and properly sealed egg yolks can be kept in the freezer for up to three months. Thaw them in the refrigerator overnight before use.

Preparation Techniques

In cooking, preparing egg yolks properly is crucial for the success of dishes ranging from creamy sauces to custards.

Separating Egg Yolks from Whites

To separate egg yolks from whites, ensure that your eggs are fresh and that you work with one egg at a time.

Crack the egg on a flat surface, then hold the egg over a bowl and transfer the yolk back and forth between the two shell halves. Let the egg white fall into the bowl as you do so.

If you prefer, use a specialized egg separator or your clean hands to let the white slip through your fingers, capturing the yolk.

Tools: Egg separator, two bowls, clean hands
Tip: Do this when eggs are cold to reduce the risk of the yolk breaking.

Whisking and Beating Egg Yolks

When whisking and beating egg yolks, aim for a smooth, even texture.

Use a fork or a whisk for a small number of yolks, and consider an electric mixer or a blender for larger quantities or when making recipes such as blender hollandaise sauce.

The goal is to incorporate air into the yolks which will lend a light and creamy consistency to your sauces and emulsions.

For sauces: Beat until yolks lighten in color and thicken slightly.
For hollandaise: Combine yolks, lemon juice, and seasoning in a blender before slowly adding melted butter while blending.

Savory Egg Yolk Recipes

Egg yolks add a rich, creamy texture to savory dishes and can transform simple ingredients into luxurious sauces, dressings, and main courses.

Hollandaise and Other Sauces

Hollandaise sauce is a classic French sauce made primarily from egg yolks, butter, and lemon juice.

To make a blender hollandaise sauce, combine 3 egg yolks with 1 tablespoon of lemon juice in a blender. Slowly incorporate melted butter until the sauce thickens.

Season with salt and a pinch of cayenne pepper for a smooth and rich sauce perfect for drizzling over steamed vegetables or eggs benedict.

Homemade mayonnaise is another versatile sauce that starts with egg yolks.

For a basic mayonnaise, whisk together 2 egg yolks, 1 teaspoon of mustard, and gradually add in 1 cup of oil drop by drop until the mixture emulsifies and thickens.

Season with salt and a bit of vinegar or lemon juice for a personalized touch.

Dressings and Marinades

Egg yolks are fundamental in creating emulsified dressings such as Caesar salad dressing.

Begin by blending together an egg yolk, a clove of garlic, two anchovy fillets, and a squeeze of lemon juice.

Gradually mix in olive oil until the dressing achieves a creamy consistency.

It is not only perfect for Caesar salad but also acts as a marinade that gives chicken or shrimp a flavorful coating.

Enriching Main Dishes

Egg yolks serve as a key ingredient in many savory dishes, presenting a powerful way to enrich flavors and textures without overwhelming the other ingredients.

For example, adding an egg yolk to mashed potatoes or duchess potatoes creates a rich, creamy blend that resonates well with comforting meals.

Similarly, an egg yolk introduced into pasta carbonara brings creaminess to the dish without needing cream.

Simply toss the cooked pasta with the cooked bacon, finely grated Parmesan cheese, and then mix in the beaten egg yolks quickly to avoid scrambling.

This way, the yolk thickens the sauce and binds all components into a delightful meal.

Dessert and Sweet Treats

When using egg yolks in desserts, you unlock rich, luxurious textures and deep flavors.

Your creations range from velvety custards to decadent chocolate delights—all infused with the unmatched creaminess egg yolks contribute.
