How do I scale Stir-Fried Udon Noodles with Spicy Sesame-Ginger Sauce for a different number of people?

The recipe is written for 3 servings. Multiply each ingredient by (your serving target / 3). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
