Begin by boiling a large pot of salted water. Once the water reaches a rolling boil, add the 4 ounces of spaghetti. Cook according to package instructions until al dente, usually about 8-10 minutes.
While the pasta is cooking, grab a skillet and melt 2 tablespoons of butter over medium heat. Once melted, add the minced garlic and grated ginger. Sauté for about 1-2 minutes until fragrant, being careful not to burn the garlic.
Next, stir in the soy sauce, honey, and hoisin sauce into the garlic-ginger mixture. Allow the sauce to simmer gently for another minute, letting the flavors meld together beautifully.
Once your spaghetti is cooked, drain it using a colander. Immediately add the drained spaghetti to the skillet with the sauce, tossing to coat each strand thoroughly.
Sprinkle with chopped scallions, and season with salt and pepper to taste. Toss everything together one last time to combine, and your dish is ready to serve!
