This is what I used! I'm making 3 patches. Serves 3-4 depending how hungry you are! Supplies are for 1 patch.
Slice the potatoes! Place them on a piece of aluminum foil. ( Heavy duty is better ) about a 10-12" piece.
Slice the onion.
Slice the garlic.
Place the onions in between the potatoes slices.
Place the garlic in between onions and potatoes.
Spread the bacon grease on the potatoes.
I saved the bacon grease from making this recipe.
Place the butter on top.
Add some salt and pepper.
Wrap up the foil to seal the steam in.
I bend the edges about 1/2" and fold a couple of times until I reach the potatoes.
I fold the ends up tight.
Ready for the oven or grill. On a hot grill cook for about 30-45mins . In the oven at 375*F for about 1 hr. Turn them over every 15-20 mins.
When opening package, BE CAREFUL THE STEAM IS HOT!! Hope you enjoy this!
