It's time to skip the store-bought stuff—this Homemade Mayonnaise is surprisingly easy to whip up and it tastes so much better! Made with only five simple ingredients, it comes together within minutes using just an immersion blender.
Add egg yolks, vinegar, mustard powder, salt and pepper to a large mason jar.
Start blending with immersion blender, at the same time, slowly begin to drizzle in oil. As the mayo starts to thicken, you can begin to pour oil a little bit faster until all the oil is combined. It should get lighter in color and look like the consistency of mayo. Taste and add any additional salt and pepper as needed.
Transfer to a smaller jar. Store in refrigerator for up to 2 weeks.
