bearcat, I have no idea what the sitting does, but there’s a big taste difference. I’ve made the exact same thing at home a 100 times and it never turns out the same as the camping version I make (both prepared exactly the same). The only difference between making it at home and my camping trips is on camping trips, it sits and marinates in lowrys and butter for a couple days in the cooler. Something about the lowrys having a couple days to soak into the taters has to be a positive. The only other difference is cooking on roaring campfire coals compared to a grill at home, so cooking at a higher temp may play into it too.
the 2-3 day wait is simply because thats how we draw up the planned meals. fish fry is always night 2 or 3 of the trip and taters go with the fish.
I’ll have to add some onions and peppers in my next go around. sounds like a great addition!
