Place the immersion blender at the bottom of the jar and blend on low. Within a few seconds, you’ll see the egg begin to turn creamy.
Keeping the blender running, slowly lift it up through the oil to bring everything together. Move it gently up and down the jar until the mixture thickens into a smooth, creamy mayonnaise. This only takes about a minute.
Notes
You can use white vinegar in place of the lemon juice.
Other mild oils work well too—light olive oil, fractionated coconut oil (which doesn't solidify), or even bacon grease if you’d like a more savory version.
Swap the dry mustard for ½ tsp prepared mustard if that’s what you have on hand.
For a spicy mayo, use spicy mustard and add a pinch of paprika or cayenne, plus a bit of coarse ground pepper.
A Note on Raw Eggs - We use fresh eggs from our own laying hens, so we know they come from healthy, well-fed birds, which gives us peace of mind when using them raw. As always, use your own judgment here. If you don’t have your own hens, look for eggs from a source you trust—and do what feels right for your family table.
