Recipe courtesy a Sundance Chef and me because he never wrote it down for me and he just told me the ingredients and I figured it out.
1-2 stick of unsalted butter
1/2 -1 cup 100% maple syrup
Salt & Pepper to taste
Bake yams at 375 for about 45-60 min depending on your oven.
Once cooled enough to handle remove skins. They should easily peel off.
While you are making this be sure to continually taste it, it is important not to get to much syrup or butter.
Using a hand or standing mixer add yams, butter and mix it for about 30 sec or so on very low just to combine butter and yams. Turning it back on low and mixing for as little time as possible add the maple syrup slowly to incorporate. Fold in salt and pepper and serve.
