1-First Step: Gather Your Ingredients and Tools Before you begin, assemble all your ingredients and equipment. You’ll need measuring spoons, either a small bowl and whisk or a jar with a tight-fitting lid, and your selected ingredients. Having everything ready makes the process smooth and takes just a couple of minutes from start to finish. This step is especially important if you’re adding optional ingredients like fresh herbs or garlic. Mince your herbs finely so they distribute evenly throughout the dressing. If using fresh garlic, either press it through a garlic press or smash it with the side of your knife to release its oils.

2-Second Step: Combine the Base Ingredients Start with your acidic components and seasonings before adding the oil. This technique helps with emulsification and flavor distribution. In your bowl or jar, add 1 tablespoon of vinegar (or lemon juice), ½ teaspoon Dijon mustard, ½ teaspoon fine sea salt, and ½ teaspoon black pepper. If you’re using any of the optional additions like garlic powder, dried herbs, or sweetener, add them now. For fresh garlic, press one small clove directly into the mixture. If you prefer a milder garlic flavor, smash the clove and add it whole you’ll remove it before serving.

3-Third Step: Whisk or Shake the Seasoning Base If using a bowl, whisk the ingredients together for about 15 seconds until the salt dissolves. If using a jar, secure the lid and shake vigorously for 10-15 seconds. This initial mixing helps dissolve the seasonings and begins to incorporate the mustard, which will act as your emulsifier. At this point, you might notice the mustard thickening slightly that’s exactly what you want! This reaction between the mustard and the acidic component creates the foundation that will help bind oil and vinegar together in a stable emulsion.

4-Fourth Step: Add the Oil and Emulsify Slowly drizzle in 3 tablespoons of extra virgin olive oil while continuously whisking. If using the jar method, pour in all the oil at once. For the bowl method, adding the oil slowly while whisking creates a more stable emulsion, though with this simple dressing recipe, either method works well. Continue whisking for about 30 seconds until the mixture thickens slightly and becomes opaque. In the jar, shake vigorously for another 20-30 seconds. You’ll know it’s ready when the dressing has a unified appearance rather than separated oil and vinegar components. The mustard should be completely dissolved, and the dressing should coat the back of a spoon.

5-Final Step: Taste, Adjust, and Use Before using, taste your dressing and adjust any seasonings as needed. If it’s too acidic, add a bit more oil or a small amount of sweetener. If it’s not tangy enough, add a splash more vinegar. This is your chance to customize the flavor profile exactly to your liking. The dressing can be used immediately, which is when it has the best emulsification and flavor combination. If you prefer, you can store it in the refrigerator for up to a week just remember to remove it 10 minutes before using, as olive oil solidifies when cold. Give it a good whisk or shake before serving if any separation occurs.
