What each ingredient does

Vegetable stock: Forms the liquid base of the soup and carries the other flavours.
Milk: Adds creaminess and mild sweetness to the broth.
Egg: Thickens the soup gently and gives it a silky, richer texture when tempered and stirred in.

The step that matters

Slowly add the egg mixture to the soup, stirring constantly. Egg proteins set at about 70°C and can scramble into lumps if the egg hits hot liquid too quickly. Tempering with a little hot soup first and adding slowly while stirring spreads the heat evenly, so the egg thickens the soup smoothly instead of curdling.
