Shoestring Fries with Truffle Aioli

By Kathy-5

Ingredients

• TRUFFLE AIOLI:
• Vegetable oil, for frying
• 2 large russet potatoes (about 1 1/2 pounds), cleaned
• 1/2 cup mayonnaise
• 1/2 cup creme fraiche or sour cream
• 1 tablespoon white truffle oil
• 1 large clove garlic, grated
• Zest of 1 lemon
• Kosher salt and freshly ground pepper
• 1/2 cup chopped fresh parsley
• 1/4 cup finely chopped fresh rosemary
• 1 tablespoon white truffle oil, for drizzling

Preparation

Step 1

Heat 2 to 3 inches of oil in a heavy-bottomed pot to 350 degrees F.
Carefully cut the potatoes into shoestrings (or matchsticks) using a mandolin fitted with the narrowest julienne blade (about 1/8-inch wide). Rinse the cut potatoes thoroughly in a bowl of cold water to remove the surface starch. Keep the potatoes in water until you're ready to fry.

For the aioli: Whisk together the mayonnaise, sour cream, truffle oil, garlic, lemon zest and salt and pepper to taste in a bowl. Refrigerate or set aside until ready to use.

Transfer the potatoes to a paper-towel-lined baking sheet and pat them dry, as dry as you can get them. I like to use a kitchen towel for this too; whatever gets them the driest.

Fry the shoestrings in batches until the potatoes are crisp and turn a nice golden brown, 2 to 3 minutes per batch. As each batch of fries comes out, transfer to a large mixing bowl and toss with some of the chopped herbs, a drizzle of the truffle oil and salt to taste. Transfer to a paper-towel-lined baking sheet. Serve with the truffle aioli.
