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

What each ingredient does

Pig's blood
Binds the filling and gives the pudding its dark color and rich body.
Half-boiled rice
Absorbs liquid and adds bulk, giving the filling a soft, sliceable texture.
Fat pork
Adds fat and moisture, keeping the pudding juicy when cooked.
Lard
Adds richness and fat, carrying flavor and helping the filling stay moist.
Bread crumbs
Absorb excess liquid and help the filling hold together.

The step that matters

Boil the casings for 15 minutes. Blood and rice mixtures set as they heat. Boiling long enough cooks the filling through and firms it, while overcooking can make it dry or cause casings to burst.

Swap the shallot

How well each one fits the dish's main ingredients (rice, pork, bread, parsley, pepper):
