Ingredients

Directions

Make the soup

  1. Combine the white stock and oyster liquor in a pot and bring to a boil.

  2. In a separate bowl, mix the rice flour and milk into a smooth batter.

  3. Once the stock is boiling, pour in the batter while stirring continuously.

  4. Let it boil for a few minutes, then remove from heat.

Finish and serve

  1. Add the oysters and cover, allowing to sit for 5 minutes without boiling.

  2. Strain in the lemon juice and serve in a hot tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White stock
Forms the liquid base of the soup.
Oysters
Provide the main flavour and texture of the soup.
Rice flour
Thickens the stock as it boils, giving the soup body.
Milk
Adds richness and softness to the batter and the finished soup.
Lemon juice
Adds acidity that brightens the rich oyster flavour.

The step that matters

Adding the batter to the boiling stock. Pour the batter in while stirring constantly so the flour disperses evenly; otherwise it can clump into lumps instead of thickening the soup smoothly.
