We make mashed sweet potatoes.
If it is more for adults we make a spicy version. I use fresh potatoes, cube them and steam them until soft, in a bowl add 2 chipoltes and a couple tablespoons of adobo sauce and some butter. Mash it together.
If it is more for kids or people who don't like spicy food I mash them and then sprinkle on a topping that is 1/2 cup flour, 1 cup crushed nuts (we LOVE cashews) and 1/2 cup brown sugar. Sprinkle that on top of the potatoes, then slice up a stick of butter and dot it across the top. Microwave for 7 minutes on high and it will form a yummy crust on top of the potatoes.
For a huge, time saving short cut I use canned sweet potatoes that are NOT in syrup. Drain them first.
If using canned, the ratio above will take care of about one really large can of sweet potatoes. If using fresh I steam 5 or 6.
