Chris Scott's Sweet Potato Fluff
Real simple...it's basically a sweet potato soufflé.
2 sweet potatoes
1 c. milk (warm)
1 stick of butter
[Wow, a stick of butter for two sweet potatoes! You don't mess around! --Ed.]
1/8 tsp. cinnamon
1/8 tsp. allspice
1/8 tsp. cloves
(all ground)
1/4 c brown sugar
6 egg whites
Peel, rough chop and boil potatoes. Drain water and put into a mixer. A bowl and a hand blender will do if you dont have a mixer. Add milk ,butter, spices, sugar and a couple pinches of salt. Blend till like mashed potatoes. Cool. Separately whip egg whites till firm, fold in with potato mixture. Place into a buttered soufflé dish and bake at 375 till puffy and done. ( when a skewer comes out dry). Garnish with marshmallow, or my new favorite -- eat it with spicy roast pork. [Yu-um. --Ed.]
re: butter ratio
Heh, yeah scary to read but normal for restaurant spuds. (Usually 1-1 by weight.) I get the same reaction from folks hearing the brownie recipe, which is why I don't volunteer that recipe while we're still eating.
