Ingredients

Directions

Prepare the filling

  1. Wash and pick the leaves of white beet and endive.

  2. Boil the leaves in a small amount of water until done.

  3. Squeeze out the water and chop the leaves finely.

  4. Mix in half the quantity of curd, an egg for each pound of mixture, Parmesan cheese, and enough grated bread to form a dough.

Shape and cook

  1. Shape the mixture into oval forms, each about the size of an egg.

  2. Dust the ravioli with flour.

  3. Bring salted water to a boil and add the ravioli.

  4. Boil until they rise to the top, indicating they are done.

  5. Serve with gravy sauce or melted butter.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Leaves of white beet
Provides the main bulk and earthy flavor of the filling.
Leaves of endive
Adds bulk and a slightly bitter green flavor to the filling.
Firm or hist curd
Binds the filling and adds moisture and mild richness.
Egg
Sets during cooking to help hold the filling together.
Grated bread
Absorbs moisture so the mixture can form a workable dough.

The step that matters

Squeeze out the water and chop the leaves finely.. Excess water from the cooked greens dilutes the filling and makes the dough soft, so the shaped ravioli may fall apart in boiling water.

Swap the endive

How well each one fits the dish's main ingredients (egg, parmesan cheese, bread, flour):

  1. Asparagusfits better
  2. Spinachfits better
  3. Chivefits better
  4. Endivethe original

Fit is the average pairing score against egg, parmesan cheese, bread, flour. Candidates are from the same food group and used in at least 100 recipes.
