How Are Truffles Prepared?

The truffle has to be cleaned of soil particles before it can be cooked or eaten. It's best to ascertain if the truffle is the edible variety, as poisonous varieties strongly resemble edible ones. At all cost avoid pealing the truffle but wash it well with water.

Truffles are grated or inserted into food preparations. Most truffle additions are done at the end of the cooking process; so as not to lose the aroma. Though the French are avid lovers of Truffles and can show one how to cook it in a million ways, here's one good recipe with Truffles:

Potatoes 6
Truffle 1 ounce grated
Melted butter 2 tablespoons
Heavy cream 2 tablespoons
Salt and pepper to taste

Bake the potatoes till soft after having pealed them.
Cut one side a little to allow it to stand on a plate.
Cut a cap out at the top and scoop out the interiors from the top.  
Mix all the other ingredients (except butter and the potatoes of course) together and stuff the potatoes.
Replace the caps and apply a coat of butter.
Bake the potatoes until golden brown.
