Hook up with a Columbia MO Brethren.
Ask them to pick up a few 5# jugs of Show Me Sauce.
Follow the recipe on the bottle for Show Me Meat Loaf.
Pretty simple. Bread crumbs and eggs (I think) are all the additional you need.
I would make it in 5# ground beef amounts (I think 3ish 1.5 loaves).
Buy couple dozen aluminum disposable bread pans (those cheap single use aluminum form pans).
Every batch is about 3 loaves.
Now the "smoke" can only get to the "top" due to the pan, so the other option is free form humongus "fatty" style loaf. I only suggested pans, for consistency. I might try an enperiment where I keep it in the pan for a while to "shape", then pop out of pan (upside down on rack) to smoke.
Then in the last half hour (temp probes on a few loaves) add the remaining Show Me per the recipe (multiplied accordingly).
As a side note, follow the recipe on a single loaf serving. That will show you what you're shooting for. Good chit. Add in the sides you're cooking, and you'll guesstimate # of loaves needed.
Let mefirst add, I never smoked meat loaf for the masses. But I do know, Show Me Meat Loaf is da Bomb!!!
