Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round beef
- Provides the meat that becomes tender during long, slow cooking.
- Flour
- Forms the dough structure that holds the filling while it cooks.
- Lard
- Adds fat to the dough, making it tender and flaky.
- Onions
- Add aroma and savory sweetness to the meat filling.
The step that matters
Pinching the dough closed. A tight seal keeps the filling and its juices inside during the long boil. A weak seal lets liquid escape and can leave the filling dry and the dough soggy.
