Bring a large pot of water to a boil. Add the spaghetti and cook according to package instructions. Reserve 1 cup of the cooking water. Drain the spaghetti and return to its pot.
Boil water for jam eggs, once boiling add egg. Boil egg for 6 mins. Then put in ice cold water. (Continue to next step)
if using frozen grilled chicken strips add to air fryer cook for 8 mins (half way shake)
While the pasta cooks, melt 4 tablespoons of the butter in a skillet over medium-low. Add the garlic and season generously with salt. Cook, stirring occasionally, until the garlic starts to soften but not brown, 1 to 3 minutes.
Stir in the gochujang, honey and vinegar, and bring to a simmer over medium-high. Cook, stirring constantly, until the mixture reduces significantly, 3 to 4 minutes; when you drag a spatula across the bottom of the pan, it should leave behind a trail that stays put for about 3 seconds. Remove from the heat.
Transfer the sauce to the pot with the spaghetti and add the remaining 2 tablespoons butter. Vigorously stir until the butter melts. Add splashes of the pasta cooking water, as needed, to thin out the sauce. Taste and season with salt and pepper. Top with the cilantro or scallions (if using) and serve immediately.
