Assemble your ingredients together.

In a saucepot over high heat, bring the broth to a rapid boil.

Reduce the heat to medium-high. Whisk in the tomato sauce until completely incorporated.

Vigorously stir or whisk in the manioc flour a little at a time until all the flour has been incorporated and the consistency is that of soft-serve ice cream or wet polenta.

Season to taste with salt and pepper.

Serve the pirão right away with your fish, meat, or vegetable stew.
