Where I come from (my first group on usenet was alt.games.creatures)we roast trolls on a barbeque.
We have one portable metal rusted one generously loaned to the group by one of the members, and we have the use of one of those lovely brick backyard ones made available by another.
We have discovered over the years that trolls have either cabbage or brocolli for brains, and therefore troll-brains are usually reserved for the vegetarians in the group, and can be either consumed in various salads or other cooked recipes.
The rest of the animal is rather "gamey" tasting, but marinated in a fairly piquant and spicy BBQ sauce are found by the non-vegetarian members of that group to be decidely delicious.
There always seems to be way too much of a troll to go round despite their diminutive stature, and so Troll-S'mores are a next day favourite.
This group has found that since the advent of the Troll BBQ, usenet trolls tend to avoid the group, and any hapless one that, ignorant of our favourite celebration, stumbles arrogantly upon the group, seems to disappear almost as rapidly as they arrived. I suppose coming face to face with an eager and delighted group hungry for troll delicacies, and always ready to use a troll thread to celebrate with a big party, and whose members fight over the honour of being in charge of the BBQs.... Well... let's just say that the encounter must be simply overwhelming.
