Sweet potatoes (mashed, roasted, or baked) are even better when topped with roasted grapes, honey and pecans.
STEP 1 - ROAST GRAPES
Set oven to 400 degrees. Place washed grapes (on stems is fine) on a baking sheet and toss with a nut oil, olive oil, or any high heat oil you want, honestly. Roast for 20 - 40 minutes (no need to wait for oven to preheat, just throw them in). They are actually hard to over-cook, by the way.
STEP 2 - PREP & COOK POTATOES
Peel sweet potatoes and cut into 1" cubes (or smaller if you want them to cook faster). Put sweet potatoes in a large saucepan and cover with 2 inches of water. Bring to a oil, then reduce heat to medium-low and simmer until tender. 10-20 minutes depending on the size of your cubes. Drain and return potatoes to pan.
OPTIONAL STEP - TOAST PECANS
Toasting nuts intensifies their flavor, but they can burn easily. Toss chopped pecans on the grape-pan that is roasting in the oven. Set a timer for 3 minutes and check to make sure the nuts aren't burning. Then set a timer for 1 more minute at a time if you aren't done with the next step
STEP 4 - ADD DAIRY & MASH
Add butter to the pan with the sweet potatoes and melt it over medium-low heat. Add milk and salt, then mash.
STEP 5 - COMBINE & SERVE
Remove the grapes from the oven. Top sweet potatoes with grapes, chopped pecans, and honey. Serve.
