Coat 20 peeled cloves of garlic in olive oil and roast them in the oven at 400 degrees for 45 minutes.
Remove from oven and let cool.
Mash roasted garlic into a puree adding lemon juice and butter into a thick paste.
Light your charcoal in the KUDU and let them burn to embers with a layer of white ash.
Adjust your grill height over the embers at medium-high heat. To locate medium-heat, place your hand over the embers and find the height you can count to 3 or 4 before having to remove your hand from the flame (approx 500 degrees).
Move your KUDU grill grate to that height and place your oysters on the grill.
Drizzle oysters with olive oil.
Add a spoonful of paste into each oyster shell.
Allow oyster to roast and sauce to bubble.
Remove from grill and add a garnish of chopped herbs and shaved parmesan.
