Step 1

In a medium saucepan over low heat, melt the butter.

Step 2

Add the onion and a pinch of salt. Sweat the onions, stirring occasionally, until tender, 8-10 minutes. If they start to turn brown, turn down the heat - you're looking for translucent and tender, not golden.

Step 3

Increase heat to medium. Stir in the flour and cook, stirring frequently, for three minutes.

Step 4

Gradually stir in the vegetable broth and continue stirring, over medium heat, until thickened to a gravy consistency, about 3 - 4 minutes.

Step 5

Stir in Tamari or soy sauce if using. Add salt and pepper to taste and serve.
