5. 5
   Add the oil in a thin, slow stream, while the blender is running, until a thick emulsion forms.

   💡The thin stream is everything: fat that goes in too fast can't bind, and the sauce breaks. For mayonnaise and hollandaise, if this happens, start with a fresh yolk and slowly add the broken sauce to it; if the sauce is too thick, thin it with a teaspoon of water.
