What each ingredient does

Sweetbreads
Gentle simmering in liquid turns them tender and moist.
Flavored stock
Cooks the sweetbreads and forms the base of the gravy.
Egg yolk
Its proteins thicken the gravy as it warms, adding richness.
Lemon juice
Adds acidity that brightens the rich sauce.

The step that matters

Adding the egg yolk and heating the sauce. Egg yolk proteins thicken the sauce, but if the gravy is too hot when the yolk goes in, or it boils afterward, the proteins tighten and curdle, leaving the sauce grainy instead of smooth.
