While Wylie Dufresne is without a restaurant of his own, he's not without friends willing to give him run of theirs.

This weekend, the former wd~50 chef will have the breakfast shift at Dominique Ansel Kitchen in the West Village, cooking up the wd~Ansel Egg Melt: scrambled eggs with a confit egg yolk, black truffle, bacon — and a few molecular gastronomy touches.

Dufresne will be using a cheese "à la Wylie," (his other restaurant, Alder, which closed last August, made its own for the house burger) and somehow crystallizing maple into flakes.

Ansel contributes the smoked English muffin it all goes inside, and the sandwich comes with a side of truffled hash browns. The wd~Ansel costs $20 and will be available from Saturday through Monday, beginning at 9 a.m. until they're sold out.
