How to make protein sauce

• 

  1.The egg whites are left over from making egg tarts

• 

  2. Stir the egg whites and add half the sugar

• 

  3.When it is slightly beaten, add the other half of the sugar

• 

  4. Heat over water and continue to stir.Whisk quickly for 30 seconds (medium-low heat, otherwise the egg whites will clump.)

• 

  5. Remove from heat and slowly add vegetable oil and stir evenly.(I took pictures while doing it alone and forgot to take a picture of pouring the oil.) Stir evenly and continue to heat over water for a while.This is the finished product.Du Niang said that the sauce made with lard is translucent, but very long.I don’t have lard at home, so I’ll use vegetable oil.
