We like to make what are called Potato Bombs! Use an apple corer and punch a hole thru the center (long ways) remove the core and break in half, Now fill the center with what ever you want!, Butter,Garlic,Ham,Cheese,peas,corn Etc. Wrap 'em in foil and lay them on the coals. Oh yeah, the core,, Just push them back in the holes to keep the fillings in! We usually buy a half dozen large russets and do this,, Last time camping I smoked a Tri Tip, chunked up the tip and added cheese and finely chopped jalapeno pepper to it!! YUM!!!
