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

What each ingredient does

Tapioca
Thickens the liquid as it cooks and sets the pudding into a soft, spoonable texture.
Rhubarb
Provides the tart fruit base that softens during baking and gives the pudding its acidity.
Sugar
Sweetens the pudding and balances the sharp flavour of the rhubarb.
Lemon rind
Adds aromatic citrus oil that brightens the flavour of the rhubarb and sugar.

The step that matters

Cook the tapioca until clear. Tapioca starch must be cooked fully in water to swell and thicken; if it stays cloudy or undercooked, the pudding will taste starchy and may not set properly.

Swap the lemon
