These are mashed and wonderful. Put two large sweet potatoes into a pot and cover with 3 inches of water. Bring to a boil uncovered and cook until you can poke a knife into them and there is just a little resistance.
Remove from water and when you’re able to skin them, remove the skin and place sweet potatoes in a bowl with 3 tablespoons room temp. butter cut into cubes. Add 1-2 teaspoon adobo sauce (most grocery stores carry little cans of chipotles in adobo sauce). With a fork mash everything together together, add a little salt to taste and ground black pepper to taste.
