Homemade Mayonnaise Ingredients
1 whole egg
1/2 tablespoon lemon juice or vinegar
1 teaspoon Dijon mustard
1/4 teaspoon salt
3/4 cup neutral-flavored oil, such as canola, grapeseed, or safflower oil
How To Make Homemade Mayonnaise
Get your ingredients and tools ready. You will need 1 egg, 1/2 tablespoon lemon juice or vinegar, 1 teaspoon Dijon mustard, 1/4 teaspoon salt, and 3/4 cup neutral oil. You can use an immersion blender or food processor.
If using an egg straight from the fridge, let it sit in warm water for a few minutes to bring it to room temperature. This is important so the mayonnaise emulsifies properly.
Add the egg, lemon juice/vinegar, mustard, and salt to your food processor or mixing jar. Starting the emulsion is key, so process or blend these ingredients for 20 seconds or so.
With the food processor running or immersion blender on, slowly drizzle in the oil. Go slowly at first so the mixture can incorporate the oil droplets. Once about a quarter of the oil is added, it will start to thicken.
Continue adding the remaining oil in a steady stream, processing or blending the whole time. This allows the oil and other ingredients to blend into a smooth, creamy mayonnaise.
Taste and adjust seasoning by adding more salt if desired. The flavor will develop more over time.
Transfer the freshly made mayonnaise to an airtight container. You can store it in the fridge for up to a week. Enjoy your homemade mayo!
