Macadamia Nut Mayonnaise

We have finally succeeded in coming up with a high quality mayonnaise recipe, that gets an A+ on both flavor and nutrition! Many of you have tried our grapeseed oil mayo, and although that recipe is delicious, I always feel a bit guilty offering that recipe knowing that grapeseed oil is not an ideal oil to use. It is very high in omega 6 (hello inflammation!), so it is definitely one you shouldn’t consume regularly. If you do decide to use it, make sure never to heat it as it will go rancid.

After a few attempts (and failures) using other oils, we finally found one that worked. Thank you macadamia nut oil. To quote Mark Sisson, “macadamia nuts are superior to all other nuts”. You can read more of Mark’s thoughts on macadamia nut oil here. This is a fantastic oil to add into your diet. It has a very mild buttery flavor, with a hint of the sweet macadamia nut, making it a perfect oil for homemade mayonnaise.
  • 1 cup unrefined macadamia nut oil
  • 1 egg
  • 1 tablespoon freshly squeezed lemon juice
  • 1/4 tsp ground mustard seed
  • Salt and pepper to taste
  1. In a blender or food processor, blend egg, lemon juice, and mustard seed.
  2. Slowly add in oil, one tablespoon at a time, continuing to blend.
  3. When the oil has all emulsified and you have a creamy mayonnaise, add in salt and pepper.
  4. Keep in a jar in the fridge. This mayo will last about a week.

      Oooh yummy. Been meaning to make some primal mayo for a while now. Does the macadamia nut oil impart much flavor or just a nice richness? I have lots of oils at home, but I know that one is a little on the pricey side.

      Wow, what a great idea!! Does it taste like macadamia nuts?

      Macadamia nut oil has a very mild flavor and smell. It works very well for making mayo. It does have a bit of a sweet flavor, and a slight hint of a nutty flavor. It is almost like a dessert mayonnaise, best paired with sweeter flavors. It was perfect for our crab cakes. We gave this mayo 4 thumbs up (two from each of us). It was great and we will definitely make it again.

      @NiNa- it is a bit on the pricey side, but you typically don't use mayonnaise everyday, so we didn't see it as a huge issue. You can check out some places online that may have macadamia nut oil for a good price, maybe try amazon. We have a few other ideas for other types of mayonnaise that we want to try out. We post those also!

      The other paleo mayo recipe I saw has 1/2 tsp dry mustard – 1/4 cup seems like a lot. But maybe ground mustard seed isn't the same as dry mustard? I'm obviously no cook.

      Also, if I don't have dry mustard or mustard seed, can I use prepared mustard? Or do you think that would mess up the emulsion with the vinegar? Thanks! đŸ™‚

      Hey Elizabeth –

      That was a typo! It IS supposed to be 1/4 tsp – thank you for catching that. We've revised it. Hopefully no one has made any mustard yet with the wrong ingredients…

      It wouldn't mess up the emulsion, and some people do use regular mustard in recipes, so you could try that out.

      Thanks again for catching that error!

      After reading your Macademia Nut Mayo recipe I was drooling. I will make some as soon as my order for the Oil arrives. Thanks for this great site. All the best.

      It is a delicious mayo recipe! We hope you enjoy it!

      I've tried a few of your recipes so far and they were great. I was wondering if avocado oil could be used in place of macadamia oil since it's about two times less expensive on Amazon.

    9. May 25, 2011

      @memento22mori- we have tried avocado oil and the flavor is just too strong. in our opinion, the macadamia nut oil is the best choice for flavor. you are welcome to try the avocado oil to see if you personally like it, or you could try mixing it with macadamia nut oil to create a more mild flavor. you would end up purchasing both oils, but you would have more left over because you would be using a half cup of each instead of a a whole cup of one. our recipe is a basic mayo recipe, you can use any oil of choice and the same consistency will occur. play around with flavors and see what you like best!

      hope that helps!

      I have made this before you changed the recipe from grapeseed oil to macadamia nut oil… I have to admit taste wise we do prefer the grapeseed oil and stay careful not to eat too much of it. Thanks for another Great one!!

      I haven't tried using Macadamia Nut Oil. So far my favorite homemade mayonnaise was using 95% Avocado oil and 5% (because we spilled some of the Avocado oil and didn't have any more) Red Virgin Palm Oil. It was kind of interesting the Palm oil made the mayonnaise very yellow, like a cheap mustard, and I was worried about the taste (For those that have never used it Palm Oil has a very strong flavor) but it was fantastic, I would love to make some more but Avocado oil is expensive so I haven't use it again.

      I believe it important to note once your mayonnaise is emulsified to stop adding oil otherwise it will return to liquid. Yes, I learned the hard way. I did a search on how to "repair" broken mayonnaise and tried the boiling water approach and it did not work this time around. All is not lost, I'm just going to use it as a creamy herb salad dressing base.

      Pre-Paleo, I used to brush chicken with regular mayo and bake it in the oven. Could I do the same using this macademia nut oil mayo?

      The Rolando Mac Nut Oil is not macadamia nut oil. It’s extra vigin olive oil with mac nut oil aroma and taste. It’s listed on the bottle and on the amazon website.

      Do you use the entire egg or just the yolk for the mayo? Thanks!
