Rinse and sort the beans, make sure there are no pebbles in your batch.
Place beans in your dutch oven and cover with about 1" of water
Bring to a boil and simmer for 1 hr, turn heat off and let sit for 1 hr
Drain
In the same dutch oven, empty now, heat vegetable oil and saute the onion and garlic until just brown. Add in the smoked turkey wings, still on the bone, and the beans.
Cover with the water and bring to a boil and cover
Move covered dutch oven into a 350 degree oven and bake until the beans start to soften - about 1 - ½ hours
When beans start to soften, remove dutch oven from the oven and pull the turkey wings out - remove the meat from the bones and add it back to your beans
Stir in ketchup, brown sugar, mustard and horseradish and bake, uncovered, until beans are tender and sauce is thick - about 2½ to 3 hours.
