Here's an idea for the fixin's, add or subtract what may be repulsive for the kiddies or others. Use an aluminum foil pan, sprayed, like 8 or 9 inches square by about 2-3" deep. I've smoked this two ways, after I partially baked it to smoke it at 225 for an hour and I baked it fully at 225 deg for about 1 1/2 -2 hours. Partially smoked/oven baked was a bit dry, fully smoked was moist, maybe needs some tweaking either way. Fruitwood, cherry with a little oak was excellent imo.
Here's my recipe for smoked Mac and Cheese , though I've made it in the oven with great success as well. Simple recipe, but I've had lots of folks ask for the recipe after trying it. Let me know if you enjoy it.
