Why Olive Oil

How does it affect flavor and texture?
Extralight olive oil has a mild taste that lets the egg and lemon shine, while still giving the mayo a silky mouthfeel. It emulsifies well, especially when you start the blend slowly, creating that classic thick but spreadable consistency.

Ingredients & Tools
What do I need for the basic keto mayo?
- 1cup (190g) extralight olive oilthe star of the show.
- 1 large egg, at room temperature (or 2 yolks for richer mayo).
- tsp salt.
- tsp Dijon mustard (optional, helps emulsify).
- tsp lemon juice or apple cider vinegar for a subtle tang.
- Pinch of black pepper.
Can I add extra flavor?
Absolutely! Toss in garlic powder, smoked paprika, fresh herbs, or a splash of hot sauce. The base is neutral enough to carry any vibe youre craving.
Which tool works best?
For the speediest emulsion, I swear by a immersion blender. It whips the oil into the egg in seconds, and cleanup is a breeze. A food processor or a sturdy whisk will do, but expect a bit more arm workout.
Why the immersion blender?
The rapid, controlled motion creates tiny droplets of oil that stay suspended, preventing the mayo from breaking. Plus, you can do it right in the bowl youll serve fromno extra dishes.
StepbyStep
How do I make it in 2 minutes?
- Set your immersion blender in a tall, narrow container (a mixing cup works well).
- Drop in the egg (or yolks) and a pinch of salt.
- Begin blending on low speed until the mixture looks a bit frothy.
- Very slowly, drizzle in the olive oil while the blender runs. The key is a thin stream at firstthink a garden hose turned to a trickle.
- When the mayo thickens (after about 60-90seconds), add the mustard, lemon juice, pepper, and any extra seasonings you like. Blend a few more seconds.
- Taste, adjust salt or acidity, then transfer to a clean glass jar.
ProTip: Preventing a Split Mayo
If the mixture looks watery, keep blending and add a teaspoon of warm water or a fresh egg yolk. This often rescues a broken emulsion.
Safety Note
Using pasteurized eggs eliminates any risk of salmonella. If youre uneasy about raw eggs, you can lightly whisk the egg over a gentle heat (about 140F) before blending.
Troubleshooting Tips
Why did my mayo split?
A split usually means the oil was added too fast or the temperature was too low. Slow the drizzle, keep the blender running, and make sure the egg is at room temperature.
Is mustard necessary?
Mustard acts as a secondary emulsifier and adds flavor, but you can skip it if youre allergic or simply dont like it. In that case, increase the lemon juice a touch to help the emulsionthe acidity compensates for the missing mustard.
Can I make it without any mustard at all?
Yesjust follow the same method, and finish with a splash of extra lemon juice or a pinch of vinegar. The result will be just as smooth, though the flavor profile shifts slightly toward tangier.
