Brûléed Mashed Sweet Potatoes

My kids, oddly enough, never went for the marshmallow-topped sweet potato confection that has graced Thanksgiving tables across our land from sea-to-shining-sea since introduced to the Pilgrims by Squanto when he saved them from starvation.  That's the story, right?  I may be getting my culinary history confused here.  The point is, as far as my family is concerned marshmallows should only be eaten melty and warm, between graham crackers with gooey chocolate.

But I digress- this is supposed to be about sweet potatoes.

This recipe came from some magazine, some number of years ago, and is delicious, and totally marshmallow-free....
