Boil 2 servings of pasta in salted water for 7 minutes. Drain and set aside, reserving 1 cup of pasta water.

Slice garlic, bacon, and onion. If using frozen mentaiko, peel the skin easily; for fresh mentaiko, cut and scoop with a spoon.

Heat 3 tbsp olive oil in a pan and sauté garlic until fragrant.

Add bacon and onion to the pan, sauté until cooked, then mix in mentaiko.

Add the cooked pasta to the pan and stir-fry for 2 minutes. If too dry, add reserved pasta water or more olive oil.

Season with a pinch of pepper and mix well.
