Smoking vegetables or fruit. Spread it out flat, or if space is tight, roll it a little and tuck in where you can....when they're done, you just grab the edges and pick it all up. They're pretty handy for keeping a meat roll or fatty tight too.
Frogmats are what brought me to BPS website to begin with. I saw a youtube vid of BP using them and had to have some.
I use themfor smoking cheeses - especially soft ones like blue or brie. Great for stuffed chicken breast, etc. keeps the stufing from falling through the grate.
And for high priced seafood - They're indispensible. Just keep a piece or two of $10-$12 salmon from sticking and falling through your grates and the frogmats start paying for themselves!
we use them for ever thing lol oops and have been using them for yrs now I have the same prototype we made back 6 or so yrs ago .. and its still going strong let me ask this BP or others have to tryed grabbing the frogmat right off the grill when your food is done <with no gloves > ??????? at 250 they are warm to the touch but wont burn you ...try that with a metal mat it will burn we have tryed it the mats will be warm but wont burn and BIG POPPAS is the place to get them for sure
