I love homemade mayonnaise.
You can so easily customize it to your preferences. It’s kind of like magic watching it thicken as you pour liquid fat into an egg. And it’s awesome to know that you can always whip up a batch if you run out of your favorite brand of store-bought mayonnaise.
Butter mayonnaise is fantastic because: butter. It makes a pretty thick mayo, and it’s smooth and, well, buttery. It’s so so good on Mayo Salmon (recipe coming soonish), in tuna salad, or homemade ranch dressing.
The one downside to butter mayonnaise is that it gets hard in the refrigerator. However, you can put your jar in some warm water to get it soft quickly.
You can use a whisk (I don’t advocate this unless you like whisking for a LONG time), a blender, or a stick blender to make this recipe. Just be careful about splatters as you pour in your butter!
As always, it’s recommended that pregnant/nursing women, children, and those with compromised immune systems use caution when consuming raw eggs. I think it’s important to use high-quality eggs if you choose to consume them raw.
Oh, and if you prefer a mayonnaise that stays soft in the fridge, check out my avocado oil mayonnaise on The Pioneer Woman’s blog. I refer to that post often to use my own recipe.
Here’s a video tutorial in case you learn better that way!

Can you use vinegar instead of Lemmon juice? I don't have any Sadly lol.

Yes, that would work! Just keep in mind what flavor the vinegar will impart to the final mayo. A mild vinegar such white wine won't be as detectable as apple cider vinegar!

Mine came out a little salty although I used a dijon mustard that might have thrown it off. I use a glass with the bottom diameter about the same size as my stick blender. Put everything in together with the butter/oil/etc on top. Blender on low start at the bottom and then move up and down. If you like ranch dressing, pick up some hidden valley ranch powder and follow directions on back using this for the mayo if you want to eliminate the rotgut vegetable oils from your diet. You might use a little more buttermilk or add some milk to the recipe if you like your dressing a little more runny at fridge temp.

This recipe makes delicious, healthy butter! I am very aware of what I put into my body and cheap seed oils is not one of them! I also think extra virgin olive oil gives mayonnaise too strong of a olive oil flavour. This recipe is perfect, thank you!

So happy you enjoyed it! Yes, olive oil can be such a strong flavor. Avocado oil is a nice alternative!

I haven't tried this yet but am excited and wanted to comment about pasteurized eggs. I pasteurize my own in sous vide which is super easy. 135° for 75 minutes. The whites cloud a little but it still is raw egg consistency.

That's brilliant, Mike! Now I want a sous vide...
