Fries

Mornay Sauce

Jalapeño Aioli

Method

Fries Preparation

  1. 1

    Prepare the Potatoes

    Peel the russet potatoes and cut them into thin fry shapes. Soak them in cold water for at least 30 minutes to remove excess starch.

  2. 2

    Fry the Potatoes

    Heat vegetable oil in a deep fryer or large pot to 350°F (175°C). Drain and dry the potatoes, then fry them in batches until golden brown and crispy, about 4-5 minutes per batch. Remove and drain on paper towels, then season with salt.

Mornay Sauce Preparation

  1. 3

    Make the Roux

    In a saucepan over medium heat, melt the butter. Add the flour and whisk together for about 2 minutes until it forms a paste.

  2. 4

    Add Milk and Cheese

    Gradually whisk in the milk until smooth, and bring to a simmer. Stir in the Gruyère cheese until melted and smooth. Season with nutmeg, salt, and black pepper.

Jalapeño Aioli Preparation

  1. 5

    Mix the Aioli

    In a bowl, combine mayonnaise, chopped jalapeño, minced garlic, lemon juice, and salt. Mix well and adjust seasoning to taste.

Assembly

  1. 6

    Combine and Serve

    Arrange the fries on a serving plate, drizzle with mornay sauce, and serve with a side of jalapeño aioli for dipping.
