Pour the olive oil into the skillet; swirl it to coat the bottom and sides; set on a stove burner, heat off.
Pour and scrape all the eggs into the skillet; turn the heat on high; wait a few seconds, just until the heat starts to permeate the pan and reach the eggs.
Gently slide the spatula from the side of the pan into the center, dragging the first coagulated eggs with it; repeat the motion, drawing in eggs from another spot.
Steadily move around the pan, constantly pulling in cooked eggs with the spatula blade, as uncooked eggs flow into the cleared space.
As you drag them, the eggs will form long rippling sheets; don’t break them up, but keep gathering them gently, into a soft mass of ruffles.
Decrease heat if the eggs sizzle—don’t let them brown.
As soon as the sides stay clear and no loose egg is flowing, turn off the heat; if there is a lot of wet, uncooked egg caught in the ruffles, more than you like, tumble the mass over gently to cook them but don’t break them up (or leave the eggs wet and soft).
Quickly divide the eggs in equal portions on warm plates, and immediately shave paper-thin flakes of truffle, a dozen or so, on top of each one.
Serve right away, as the heat releases the aroma of truffle.
