Whisk the eggs yolks with 1 teaspoon water in a mixing bowl. Slowly whisk the canola oil into the eggs until an emulsion forms. Slowly add 1/2 cup lukewarm water and the lemon juice when the emulsion becomes too thick.

Make sure the sauce is creamy and fully emulsified before adding the truffle oil. Whisk in the truffle oil and add the salt and pepper. Add more water until the sauce turns off-white in color and has the consistency of ketchup. Taste for seasoning and acid, and add salt and lemon juice accordingly.

Serve on top of fresh, hot French fries tossed with a little salt and pepper, and sprinkle with grated Parmesan.

Cook's Note: All the ingredients should be at room temperature to prevent the sauce from breaking. The sauce should be creamy and not too runny.

Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell. For recipes that call for eggs that are raw or undercooked when the dish is served use shell eggs that have been treated to destroy Salmonella, by pasteurization or another approved method.
