Ingredients

Directions

Make the base

In a dry pot over medium heat, add the bacon or fat salt pork and sliced onions, and fry until browned, stirring constantly to prevent burning.
Add pepper, salt, and sugar to the pot.

Simmer the stew

Pour in the cold water and add the soaked and drained peas.
Cover and boil gently until the peas are soft, stirring frequently.
Gradually stir in the oatmeal mush and simmer for 20 minutes.

Serve

Serve hot.

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

What each ingredient does

Dried peas: Break down during long simmering to thicken the stew and give it body.
Oatmeal mush: Stirred in at the end to thicken the broth further and add a creamy texture.
Bacon or fat salt pork: Renders fat that browns the onions and adds savory richness to the stew.
Onions: Browned at the start to build sweetness and deep savory flavor.
Sugar: Balances the saltiness of the pork and rounds out the flavor with mild sweetness.

The step that matters

Fry the bacon and onions until browned, stirring constantly. Constant stirring over medium heat keeps the onions and fat from scorching, while browning creates the Maillard flavors that give the stew its savory depth. Burnt sugars and fat taste bitter and cannot be fixed later.
