Wash your hands thoroughly after handling raw egg yolks to prevent bacterial cross-contamination.
Combine 1 piece egg yolk, 1 tsp water, 1 tsp fresh lemon juice, and 0.25 tsp salt directly into the bottom of a tall blending cup that fits the head of your immersion blender.
Watch out
The blending cup must be narrow enough to barely fit the immersion blender head, otherwise the small volume of egg yolk will not create a vortex to start the emulsion.
