• Unsalted Butter2 tbsp
• Yellow Onion, finely chopped1 medium
• Vegetable Oil, for frying~6 cups
• Frozen Shoestring Fries16 oz

Method

1. Make the animal sauce. Whisk mayonnaise, ketchup, relish, vinegar, mustard, and ¼ tsp salt together. Set aside.
2. Caramelize the onion. In a large skillet over medium-high heat, melt butter. Add onion and ¼ tsp salt. Cook, stirring occasionally, until well browned, 8–10 minutes. Transfer to a small bowl.
3. Heat the frying oil. Pour vegetable oil to a 2-inch depth in a Dutch oven or heavy pot. Heat over medium-high until a thermometer registers 375°F.
4. Fry the fries. Using a spider or slotted spoon, lower half the fries into the oil. Fry, stirring to prevent sticking, until golden brown, 4–5 minutes. Transfer to a paper towel-lined baking sheet and season with salt. Repeat with remaining fries.
5. Make the cheese sauce. In a small heatproof bowl, microwave the American cheese and milk in 30-second increments, whisking between each, until fully melted and smooth, 2–3 minutes total.
6. Assemble. Pile fries on a platter or tray. Pour cheese sauce over top, then scatter caramelized onion. Drizzle generously with animal sauce.
