Boiled Squash

Ingredients

Directions

Prepare the squash

Peel the squash and cut it into 1‑inch pieces.

Make the sauce and cook the squash

Bring salted water to a boil in a pot and add the squash pieces; boil until tender.
Melt the butter over medium heat in a separate pan and stir in the flour until brown.
Gradually add the boiling water to the butter‑flour mixture, seasoning with salt and pepper.
Once the sauce boils, set it aside until the squash is done.

Combine and serve

Drain the squash and mix it with the hot brown sauce, then serve immediately.
Alternatively, mash the boiled squash through a colander, heat with salt, pepper, and butter, and serve.

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

What each ingredient does

Squash: Forms the main body of the dish, turning soft and tender when boiled.
Butter: Adds fat and rich flavor, and forms the base of the sauce with the flour.
Flour: Thickens the sauce as its starch swells in the hot liquid, and browning adds nutty flavor.
Boiling water: Forms the liquid that the butter and flour thicken into a sauce.

The step that matters

Adding the boiling water to the butter‑flour mixture. Flour starch clumps when liquid is poured in all at once. Adding the boiling water gradually while stirring lets the starch disperse evenly, so the sauce stays smooth and thickens without lumps.
