The Definition of “Emulsify” And Why It’s Important

If you’re a fan of cooking shows or the culinary arts in general, you’ve probably heard the term emulsify get thrown around. But if you’re not a professional chef or have a background in hospitality, you may not know exactly what that means. So, to help you wrap your mind around this important concept, learn the definition of “emulsify” and why it’s important to the preparation of food.

What Does Emulsify Mean in Cooking? 

The standard emulsify definition is to combine two ingredients that don’t normally mix easily. In cooking, this usually means an oil or a fat and water or a water-based substance like broth or vinegar. Oil and water will naturally repel each other, which means you must do some vigorous mixing to make sure these substances can be combined in the same recipe. You will also need to add what is called an emulsifier to ensure the mixture stays uniform and doesn’t break apart when you’re done whisking. 

Common Examples of Emulsifiers 

Based on the emulsify definition, good emulsifiers will have properties that attract water on one end and oil on the other. Although this may sound complex, chances are you have several emulsifiers in your kitchen right now. 

Common household emulsifiers include:

  • Egg Yolk
  • Cheese
  • Butter
  • Mustard
  • Honey
  • Catsup
  • Miso
  • Garlic Paste

Once you understand the definition and concept of how to emulsify food, it’s fairly easy to identify common emulsifiers. No matter how hard you whisk them, an oil-based and a water-based substance will always separate without an emulsifier to bond them. So, these secondary ingredients are essential to keeping the mixture uniform.

What is the Emulsification Process? 

The process chefs use to emulsify food is typically started by combining the two liquids slowly while whisking or stirring vigorously. For the best results, chefs typically use a blender or food processor, but a whisk or hand beater will also suffice. When added drop by drop, the liquids will become easier to mix because tiny amounts of each will be suspended in the other.

While you emulsify the food, it also helps to keep an eye on the Ph and temperature. These factors play an important part in the texture and definition of your dish. Acidic liquids like lemon juice or vinegar can help change the pH of the mixture. Also, note if the ingredients are too hot or too cold it will impair the process. So, pay close attention to how the ingredients are coming together. 

How Does Emulsifying Help in Cooking? 

Now that we’ve covered what does emulsify mean in cooking?, let’s take a look at when it comes in handy. Chefs use emulsification to create sauces and condiments that combine the unique flavors of the ingredients. Although they don’t mix easily, oil-based and water-based ingredients often compliment each other nicely and create a mixture that works well as an added dressing. 

Popular concoctions made through emulsification include:

  • Vinaigrettes
  • Aioli
  • Pesto
  • Hollandaise Sauce
  • Bearnaise Sauce
  • Buttermilk
  • Ice cream
  • Bouillabaisse

There are many different dishes and ingredients made with emulsification. Once you understand the emulsify definition, it opens up a whole new world of flavors and recipes. You can employ this in your own cooking. Or at the very least, you’ll understand the term next time it comes up in your favorite cooking show.
