• Bring a medium pot of salted water to a boil. Wash and dry produce. • Peel and mince garlic. Trim scallions; cut crosswise into 1-inch pieces. Thinly slice 1/4 of the scallion greens; set aside. Trim and peel carrot; grate on the largest holes of a box grater. Roughly chop peanuts.

• In a small bowl, whisk together sweet soy glaze, stock concentrate, half the Szechuan paste, half the vinegar, half the peanut butter, 11/2 tsp sugar, 1/4 cup water, and chili flakes to taste until smooth. (For 4 servings, use all the Szechuan paste, vinegar, and peanut butter, 3 tsp sugar, and 1⁄3 cup water.)

• Heat a drizzle of oil in a large pan over medium-high heat. Add pork*. Using a spatula, press into an even layer. Cook, undisturbed, until browned on bottom, 3-4 minutes. • Break up meat into pieces and continue cooking until pork is cooked through, 2-4 minutes more. Rinse shrimp under cold water; pat dry with paper towels. Heat a drizzle of oil in a large pan over medium-high heat. Add garlic, scallion pieces, and shrimp to hot pan. Cook, stirring, until shrimp is opaque and cooked through, 2-3 minutes.

• Add garlic and scallion pieces to pan with pork; cook until fragrant, 1-2 minutes. • Stir in sauce. Cook until sauce has reduced and thickened slightly, 1-2 minutes.

• Add 3/4 of the noodles to pot of boiling water (we sent more); cook, stirring occasionally, until tender, 1-2 minutes. Drain and thoroughly rinse under cold water, at least 30 seconds. TIP: This stops cooking and helps prevent sticky noodles. • Add cooked noodles, carrot, and 1 TBSP butter (2 TBSP for 4 servings) to pan with pork mixture. Toss until noodles are warmed through and everything is thoroughly combined, 1-2 minutes. (TIP: If needed, stir in water a splash at a time until pasta is thoroughly coated in sauce.) Taste and season with salt and pepper.

• Divide stir-fry between bowls. Top with sliced scallion greens, peanuts, and remaining chili flakes to taste. Serve.
