Karl’s Keto Real Mayonnaise

Normally I use Kraft’s Fat Free Mayonnaise for most things, because of Jan’s diet restrictions. Jan suggested that with the general theme of my blog, “That Fresher is Better,” I should try my hand at real mayonnaise.

I looked at several recipes to get the general feel for this famous sauce. Some recipes were overly complicated and added things that just didn’t seem to belong. I stripped my recipe to the bare minimum and, to keep it ketogenic, I did not add any sugar.

Karl’s Keto Real Mayonnaise


1 egg yolk
2 Tbs. lemon juice
½ tsp. dry mustard (Colman’s)
¼ tsp. Flor de Sal (sea salt)
¼ cup extra virgin olive oil
¼ cup grape seed oil
1 tsp. water


1. Separate the egg and save the white for breakfast.

Tip: Make sure all ingredients are at room temperature.

2. Put the egg yolk in the bottom of a blender and pulse to blend.

3. Add the lemon juice, salt, mustard, and one tablespoon of olive oil and blend on the lowest setting for 30 seconds.

Tip: The dry mustard acts as an emulsifier to keep the yolk, lemon juice and oil from separating.

4. Slowly drip the rest of the olive oil into the open top of the blender while the blades are still spinning on the lowest setting.

Tip: The whirling blades of the blender should cause the yolk, lemon juice and oil to fluff up into a thick cream. Do not start adding the rest of the oil until it has reached this state.

5. Slowly drip the of the grape seed oil into the blender.

Note: Some of the recipes suggested that using strait olive oil resulted in a heave taste. I decided to try the grape seen oil that one recipe suggested.

6. If the mayonnaise it too thick add some water to thin it out.

Tip: Many recipes call for using as much a much as a cup of oil for one egg yolk.  Julia Child recommends that beginners should use no more than half a cup. This is because if you add too much, or add the oil too fast, it will not be emulsified and the oil will float to the top of the mayonnaise. My thought is: you should make only as much as you need and not try to see how much oil you can pack into one batch.
