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

What each ingredient does

Flour
Forms the structure of the dumpling batter as it steams.
Baking powder
Releases gas as the batter heats, helping the dumpling rise and turn light.
Blueberries
Add pockets of fruit flavor and juice that colour the dumpling batter.
Cornstarch
Thickens the sauce as it cooks with the boiling liquid.
Sugar
Sweetens the sauce and helps give it body.

The step that matters

Dissolve cornstarch in sweet milk before adding it to the boiling mixture. Cornstarch clumps if it hits hot liquid dry. Dissolving it in cold liquid first lets the starch disperse, so when the sauce boils it thickens smoothly instead of lumpy.

Swap the lemon

How well each one fits the dish's main ingredients (flour, sugar, milk, butter):
