Homemade mayonnaise is a simple oil-in-egg emulsion, and an immersion blender makes it nearly foolproof in under two minutes. The base uses lemon juice and Dijon for a clean, balanced flavor, and the method is stable enough to hold in the fridge for a week. Four variations — herb, smoky, spicy, and truffled — are included so the recipe adapts to whatever you're serving.

Instructions
Temper and Set Up: Ensure the egg and oil are at room temperature, ideally 68–72°F (20–22°C)—this helps the emulsion form instantly. Fit your immersion blender head into a tall, narrow jar that just fits it; this confined space is key to success.
Load the Jar: Add in order: egg, lemon juice, Dijon, white wine vinegar, salt, and a pinch of sugar. If using, add the garlic, white pepper, and lemon zest. The seasonings at the bottom ensure they fully incorporate.
Add the Oil: Gently pour the neutral oil over the top so it sits above the egg mixture in a distinct layer. Do not stir.
Emulsify (30–45 seconds): Place the blender head flat on the jar’s bottom, directly over the egg. Start blending on high. You’ll see a thick, pale ribbon forming immediately. Keep the blender anchored for about 10 seconds, then slowly raise it as the emulsion climbs, finishing when all oil is incorporated. Sensory cues: glossy, thick, and holds soft peaks when a spoon is lifted.
Adjust and Stabilize: Taste. Add a pinch more salt or a few drops of lemon juice if desired. Pulse 2–3 seconds to incorporate. If the mayo looks slightly loose, blend 5–10 seconds more; it will tighten as you incorporate residual oil and air.
Flavor it (optional): Fold in one variation: herbs, smoked paprika, sriracha, or truffle oil. For herbs, fold gently to keep the color vibrant green. For sriracha, whisk to a uniform coral hue.
Store Safely: Transfer to a clean jar and refrigerate at or below 40°F (4°C). Use within 1 week. Always use clean utensils to avoid contamination.
If it Breaks, Fix it: In a clean jar, add 1 tbsp water and 1 tsp Dijon. Begin blending, then slowly drizzle in the broken mayo while blending continuously. It will re-emulsify and become creamy again.
Alternative Whisk Method (8–10 minutes of active whisking): In a medium bowl, whisk egg, Dijon, lemon juice, vinegar, salt, and sugar until smooth. While whisking constantly, add oil drop by drop for the first 2 tbsp, then in a thin steady stream. You’re looking for a pale, glossy, thick consistency and a faint lemon-mustard aroma. Set the bowl on a damp towel to stabilize while whisking.
Notes
Lisa’s Tips:
Use pasteurized shell eggs for peace of mind, or buy pasteurized liquid whole eggs and measure 3 tbsp per egg.
Oil Matters: grapeseed and sunflower are neutral; light (not extra virgin) olive oil adds subtle fruitiness. Avoid full extra virgin—its polyphenols can turn the mayo bitter when blended.
Salt Type: Diamond Crystal kosher is less dense than Morton. If using Morton, start low and adjust.
Extra-Stable Mayo: Add 1 tbsp cold water to the jar before blending—water hydrates proteins and makes a silkier, more spreadable emulsion.
Garlic Paste Trick: Smash garlic with a pinch of salt to a smooth paste to avoid any fibrous bits.
Too Thick? Whisk in 1–2 tsp cold water until it loosens to the desired texture.
Serving Suggestions:
Color and Texture: Serve when pale ivory, glossy, and thick enough to hold soft peaks.
Plating Ideas: Swipe onto a plate and top with blistered shrimp, charred asparagus, or tomato wedges; or spoon into a ramekin and finish with a drizzle of olive oil, lemon zest, and flaky salt.
Pairings: Crispy fries, crudités, grilled fish, roast chicken sandwiches, or artichokes. A crisp white wine (Sauvignon Blanc) or chilled pilsner complements the richness.
Culinary Context:
Mayonnaise is a pillar of French cuisine, likely popularized in the 18th century and beloved worldwide. This immersion-blender technique is a modern chef’s shortcut that yields a reliable emulsion in seconds—no bicep workout required.
Optional Advanced Instructions:
Make-Ahead: Mayo keeps up to 1 week refrigerated. Herb and truffle variations are best within 2–3 days for peak aroma.
Parallel Prep: Zest and juice your lemon while the egg warms to room temp; prep garnishes in the downtime.
Beginner Alternative: If the immersion method feels fast, use the whisk method for more control—start with just the yolk instead of a whole egg for an even thicker texture.
