What is mustard aioli made of?

Mustard aioli is a flavorful condiment made by emulsifying oil and egg yolks with the addition of mustard for a tangy kick. It can transform sandwiches, burgers, grilled meats and fish, and vegetables into something truly special. Read on to learn all about the ingredients that go into this versatile sauce.

The Main Ingredients

Mustard aioli contains just a few main ingredients:

  • Oil – Usually a mild, flavorless oil like canola, vegetable, or grapeseed.
  • Egg yolks – Egg yolks act as the emulsifier to bind the oil and water.
  • Mustard – Adds tangy, spicy flavor. Dijon and whole grain mustards work best.
  • Lemon juice – Brightens up the flavor with acidity.
  • Garlic – Provides aromatic flavor.
  • Salt – Seasons the aioli.

By blending these simple ingredients together, you get a rich, decadent sauce perfect for spreading, dipping, and drizzling.

The Purpose of Each Ingredient

Let’s take a closer look at why each ingredient is important in mustard aioli:

Oil

Oil is the main component of any aioli or mayonnaise-style sauce. It makes up about 3/4 cup of the total recipe. The oil provides richness, creaminess, and a smooth texture. For mustard aioli, a neutral-tasting oil works best. Good options are:

  • Vegetable oil
  • Canola oil
  • Grapeseed oil
  • Sunflower oil

Stay away from strong-flavored oils like olive oil or nut oils, which can overpower the other ingredients. The oil should be added very slowly at first to properly emulsify with the egg yolks.

Egg Yolks

Egg yolks act as the emulsifier or binding agent in aioli. Two to three egg yolks are typically used. The lecithin in egg yolks helps blend the oil and water together into a stable emulsion. Egg yolks also provide richness from their fat content. Make sure to use ultra-pasteurized eggs for safety when consuming raw yolks.

Mustard

Mustard is what gives mustard aioli its distinctive flavor. You can use yellow mustard, but Dijon and spicy brown mustards are better options. The tanginess and spiciness of the mustard pairs perfectly with the rich creaminess of the aioli. Use about 1-3 tablespoons of mustard depending on your taste preferences.

Lemon Juice

A teaspoon or two of fresh lemon juice brightens up mustard aioli. The acidity cuts through the richness and enhances the flavor of the mustard. Bottled lemon juice works as well.

Garlic

Garlic provides a savory, aromatic flavor to the aioli. Use 1-2 cloves minced or crushed. Raw garlic gives the strongest flavor. Letting the minced garlic sit for 10-15 minutes before adding mellows out the harshness.

Salt

Salt is added to taste to season the aioli. Start with 1/4 teaspoon sea salt or table salt. You can always add more later once all the ingredients are emulsified.

Step-By-Step Instructions

Here is a step-by-step guide on how to make mustard aioli:

  1. Separate 2-3 egg yolks from the whites. Place the yolks in a medium mixing bowl.
  2. Mince 1-2 cloves of garlic and let sit for 10-15 minutes to mellow.
  3. Measure out 3/4 cup neutral oil like canola or grapeseed. Have ready near the mixing bowl.
  4. Add 1-2 tsp lemon juice and 1/4 tsp salt to the egg yolks.
  5. Whisk together the yolks, lemon juice and salt until smooth.
  6. Slowly drizzle in a few drops of the oil while whisking constantly. Keep whisking until the oil is fully incorporated.
  7. Continue whisking in the oil, a few drops at a time. As the emulsion begins to form, you can start adding in slightly bigger drizzles.
  8. Mix in the garlic, 1-3 Tbsp mustard, and a pinch more salt. Taste and adjust seasonings as desired.
  9. Mix in any additional ingredients like herbs or spices.
  10. Cover and refrigerate for at least 30 minutes before using to allow flavors to meld.

The aioli will keep refrigerated for 4-5 days. The flavor may mellow slightly over time.
