Notes

Avocado Oil: I like avocado oil in this healthy mayo the best, but have used light tasting olive oil in the past. I find the light tasting olive oil to still have too much olive oil flavor. Avocado oil is very neutral tasting.
Eggs: Use as fresh of eggs as possible. I have been making this recipe using raw, organic, store bought eggs since 2015 and have never had an issue. (We go through 1 jar a week). If you have a compromised immune system, or prefer a pasteurized egg, you can buy pasteurized eggs from the store or pasteurize them yourself by cooking the eggs in warm water at 140ºF for 3 minutes.
Using a Different Container: The only container I recommend using to make this healthy mayo is a wide mouth pint mason jar, or wide mouth quart mason jar if you're making a double batch. If your container/jar is too large it won't emulsify properly and your mayonnaise will break. Some immersion blenders come with their own container. That may work. But to be sure, stick with the wide mouth pint mason jar.
Using a Blender: You can use a regular blender, but it's a different process. You will whip the egg yolks, lemon juice and salt first, then *slowly* drizzle in the oil. I've had this method not work too, if you don't drizzle it on slow enough. And when it does work, it's so much more work scraping out all the mayonnaise after. Honestly, immersion blender and mason jar are the easiest and more efficient and way to go.
If The Mayo Breaks: If for some reason your mayonnaise did not emulsify (even while using a wide mouth mason jar and immersion blender), you can usually save it by adding in 1 more egg yolk to the mayo that didn't emulsify. Be sure you trap the yolk within the stick blender, then leave it down there for a full 20 seconds, then slowly lift it up. This should save your mayonnaise! But honestly, I've been making a jar a week since 2015, and have never had it not work.
Freezing: Sadly mayonnaise does not freeze and thaw well. I would not recommend freezing.
