Remove the stems of the portobello mushrooms. Place the caps on a plate with the gills side up. With a paring knife, cut the mushrooms in half and begin to scrape the gills away from the cap where they meet. You will notice that the gills look like small, rectangular chopped truffles as they drop onto the plate. Repeat with the other mushroom halve. Set aside the gills for the "truffles" to sprinkle on top of the pasta dish when finished. Reserve the remaining mushroom for later use.
Cook until the whites are just set and the yolks begin to thicken but are not hard. Remove the eggs with a slotted spoon to a warmed plate (in the same order they went into the pan). Check out Linda's tutorial on Poached Eggs.
Toss the pasta with the butter, truffle oil, parmesan cheese, salt, and pepper. If it seems to dry, add a few more tablespoons of the cooking water and toss again.
Divide the pasta among 6 individual warmed serving bowls. Top each portion with a poached egg, sprinkle the reserved gills or "truffles" over the top, and serve immediately.
Makes 6 servings.
* The secret to pretty poached eggs is using very fresh eggs which will hold their shape better and produce fewer "angel wings" in the liquid.
