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

What each ingredient does

Sago
Thickens the liquid as its starch swells and gelatinizes during simmering, forming the jelly.
Tapioca
Adds starch that thickens the liquid and helps it set into a soft, jelly-like texture.
Hartshorn shavings
Ammonium carbonate that helps the liquid set into a firm jelly when cooled.
Rice
Adds starch that contributes body and thickening to the simmered liquid.
Pearl barley
Adds starch that contributes body and thickening to the simmered liquid.

The step that matters

Simmer for three hours. Starches such as sago and tapioca need sustained heat in liquid to fully swell and gelatinize. Stopping early leaves grains firm and the jelly weak or gritty.

Swap the cinnamon

How well each one fits the dish's main ingredients (rice, barley):

  1. Cinnamonthe original
  2. Turmericfits about as well
  3. Celeryfits about as well
  4. Thymefits less well

Fit is the average pairing score against rice, barley. Candidates are from the same food group and used in at least 100 recipes.
