Ingredients For Mentaiko Pasta Recipe
Spaghetti: The base of the dish, providing a neutral canvas for the flavorful sauce.
Butter: Adds richness and a silky texture to the sauce.
Mentaiko: Spicy cod roe that brings a unique umami flavor to the pasta.
Soy sauce: Enhances the savory taste and adds depth to the sauce.
Olive oil: Helps to combine the ingredients and adds a subtle fruity note.
Nori: Chopped seaweed used as a garnish, adding a touch of the ocean.

Technique Tip for This Recipe
When preparing mentaiko, be sure to gently remove the roe from the sac using a spoon. This ensures that the delicate roe remains intact and evenly distributes throughout the pasta. Additionally, when melting the butter in the pan, keep the heat at medium to prevent it from browning too quickly, which can alter the flavor profile of the dish. Finally, when adding the soy sauce and olive oil, make sure to stir well to create a cohesive sauce that will thoroughly coat the spaghetti.
