Step 1

Put the sweet potatoes in a steamer basket and place in a large pot of simmering water. The water should be 1 inch below the bottom of the basket. Cover and steam over medium-high heat until the sweet potatoes are fork-tender, about 20 minutes.

Step 2

Remove the steamer basket, pour out the water, and dump the sweet potatoes back into the pot. Add the butter and salt and mash with a potato masher. Add the chile and sauce and continue mashing to combine. Serve immediately.
