Have you ever looked at the ingredients for mayonnaise?

It contains things like oil and vinegar–two liquids that never get along. And yet, some how in your jar of white gloopity-glop, they’ve come together in peace. All for the sake of your sandwich. Maybe that’s why they call it Miracle Whip? Well, this little miracle is called an emulsion.

What’s an emulsion?

An emulsion is a mixture of teeny-tiny particles that are disseminated in another material, but do not separate out of that material. Basically, two liquids that don’t usually mix are dispersed throughout each other.

How does this happen?

An emulsion occurs when one ingredient is slowly added to another ingredient and both of those ingredients are being mixed up simultaneously. Small particles of one liquid are spread through the other liquid. Then, an ingredient called an emulsifier is added to keep those particles from separating. The emulsifier is attracted to both oil and water, so it acts as a binder.

Ok, so what about mayonnaise?

Well, mayonnaise is an emulsion! To make an emulsion, you need three key players–1. vinegar/acid 2. oil and 3. egg. Vinegar and Oil never stay friends for long. When they get together, they always end up separating. But then good ol’ egg comes in. Egg is Switzerland. It’s a peace treaty. It’s going to let vinegar and oil make amends and everybody can then get along for good. Egg yolk contains lecithin, which is a phospholipid that on one end is attracted to vinegar and on the other end of the molecule, is attracted to oil. When the ingredients are incorporated very S-L-O-W-L-Y (because in all good peace talks, patience is prudent), over time they come together into a beautiful, creamy mixture.

Sometimes peace talks fail.

Ok, it’s true. I wish it weren’t so, but peace talks aren’t always successful–and emulsions aren’t either. If the oil is added too quickly, the end result could look like the picture on the left. The mixture will be smooth and liquids will be dispersed, but not fully. It’s not a total wash though! I’ve had a few failed emulsions and still used the mixture as a dressing for dishes like my Broccoli Salad (that I’ll share soon…oh it’s so good!).

If the emulsion is broken–that is, if it did come together and then later falls apart–then you can try whipping it up again with another egg yolk.

So, let’s have a go at it, shall we?

Homemade Mayonnaise

adapted from Mommypotamus
makes about 1 cup


3 egg yolks from pastured hens *
1 Tbsp. lemon juice**
1/2 tsp. unrefined sea salt
2 tsp. raw honey or Grade B maple syrup (find it HERE)
1 tsp. ground mustard
1/2 cup coconut oil (find it HERE)
1/2 cup olive oil

*room temperature eggs work best, also there is a 1 in 20,000 risk of raw eggs containing Salmonella (eat at your own risk), disclaimer
**lemon juice is an acid that can be used in place of vinegar–it gives it a brighter taste in my opinion


In a food processor or blender, blend the egg yolks for about 1 minute. Add the lemon juice and blend for another 30 seconds. Then add the sea salt, sweetener, and mustard and pulse to combine.

Turn on the food processor and slowly pour the oil into the egg mixture. When you pour the oil, the oil stream should be very thin–like you are pouring the tiniest amount of oil at a time, while still actually pouring oil. The oil pouring process takes 3-4 minutes, so don’t feel like you have to rush. The key to successful, creamy mayonnaise is patience here. :)

How long does it last?

Once the mayonnaise is made, store it in the fridge. In terms of how long it lasts, most say two weeks. Funny thing is, I always eat it up before then! It’s so easy to make, I just whip up another batch!

What about you? Do you make homemade mayonnaise? Do you ever add any herbs like dill or chives? On what foods do you like to use mayonnaise?

  1. Hi, this mayonnaise looks awesome, I love the fact that you used coconut oil too as well as olive oil. I have a question, how long will this keep in the fridge? Thanks in advance…

    • Allison Jordan says:

      Clare, some sources say it lasts one week, some say two. Honestly, I always use mine up before a week is over, so I’ve never had to find out! :)

      • From Nourishing Traditions (p. 137 in my copy) by Sally Fallon, the mayonnaise will last about 2 weeks. If you add whey (the liquid from straining yogurt) and let the mayo sit on the counter for about 7 hours well covered, it will keep much longer…several months in fact.

  2. Alison Claudy says:

    Do you use extra virgin olive oil?

    • Allison Jordan says:

      Alison, yes I do. I’ve seen some other versions recommend using olive oil that isn’t “extra virgin”, but EVOO is all I ever have on hand so I always use that and it comes out great!

    hi…first time stopping by and am enjoying exploring your site…great info. As a matter of fact tonite I was wondering about how it would be to make my own mayo and there was your recipe! Perfect timing.! Looking forward to keeping up with your site and posts! Thanks

  4. Great & easy recipe ….& nothing to do with commercial …This is alive & full of flavour !!

  5. I LOVE homemade mayo – I use avocado oil and it turns out beautifully & tasty!! I would love to try with coconut oil but maybe refined (I know) so there isn’t a coconutty flavor too it.

    I make a Chipotle Mayo too – I add the canned Chipotle peppers with adobo sauce!! Amazing!! We put it on sandwiches, meats, etc! Try it!!

    Thanks for the advice – I have so much trouble making my baconnaise!! It almost always fails! The bacon fat is either too heavy or too warm – I wish I knew the magic to make it successful 100%!!
