Ingredients

  • 1 cup avocado oil
  • 1 egg
  • 1 tbsp apple cider vinegar
  • 1/2 tsp sea salt

Instructions

  • Add the egg, oil, vinegar, and salt to a jar wide enough to fit the immersion blender. I use a pint-sized wide-mouth mason jar. 
  • Put your immersion blender in all the way to the bottom of the jar so it covers the egg, and then turn it on high.
  • Blend it without moving for about 10 seconds, then slowly move it up and down until the mix thickens into mayo. This should take 10-20 seconds.
  • If you’re using a mason jar like me, just grab a lid and store it in the fridge. Otherwise, scoop your mayo into any container with a lid.
  • For the freshest flavor, use it within 1-2 weeks.

Notes

  • Use Room-Temperature Ingredients: Cold ingredients don’t mix well. Keep everything at room temp to avoid separation.
  • Pick Quality Ingredients: Few ingredients mean no room for shortcuts. Use fresh eggs, neutral oil, and good vinegar or lemon juice for bold flavor.
  • Skip the Bowl: Use a tall, narrow jar. It forces the ingredients to emulsify quickly and evenly.
  • Stick with an Immersion Blender: Food processors can overdo it. Immersion blenders are faster, easier, and deliver perfect consistency.
  • Experiment with Flavors: Add garlic, herbs, mustard, or swap vinegar for lemon juice. Create your own spin on this kitchen staple. No fuss. No extras. Just a simple recipe done right.
