Cooking Sequence & Checkpoints

1
Layer Ingredients in Jar⏱️ 1 min

Place whole egg, 1 tbsp lemon juice, 1 tbsp water, 1 tsp Dijon mustard, and 0.75 tsp kosher salt in the bottom of a narrow jar. Pour 1 cup neutral oil on top and rest 15 seconds.

✓ Checkpoint: Egg settled on bottom, oil floating on top.

2
Anchor Blender⏱️ 1 min

Submerge immersion blender head firmly against bottom of cup, trapping the egg yolk.

✓ Checkpoint: Blender head flush against bottom.

3
Start Vortex⏱️ 1 min

Turn on high speed without lifting. Watch thick white mayonnaise bloom upward for 20 seconds.

✓ Checkpoint: Heavy white emulsion at base.

4
Slow Lift⏱️ 1 min

Slowly tilt and draw blender upward to incorporate the remaining top oil layer.

✓ Checkpoint: Stiff, velvety homemade mayonnaise.

🛡️ Food Safety & Internal Temperature: 160°F (71°C) USDA egg safety standard / Use pasteurized shell eggs & refrigerate at ≤40°F (4°C)Homemade mayonnaise is an unheated raw-egg emulsion and does not reach the 160°F (71°C) USDA temperature required to eliminate Salmonella. Always use pasteurized shell eggs—especially when serving pregnant individuals, young children, older adults, or immunocompromised guests—and store refrigerated at ≤40°F (4°C) for up to 5–7 days.

🔬 Why It Works:

The Vortex Physics of Narrow Jars: Resting the immersion blender firmly on the base creates a vortex that draws down the floating oil in micro-droplets directly into the spinning blades, preventing breakage.

⚠️ Troubleshooting:

Broken liquid mixture: Add 1 tsp warm water, sink blender to bottom, and restart.
