Originally introduced from Korea, mentaiko has taken on a life of its own in Japan. It's salty, savory, sometimes spicy, and has this satisfying little pop when you bite into it. These days, it's everywhere — from lunch boxes to fusion pastas.

Not just one kind: different types of mentaiko 🌶️🍋

One of the coolest things about mentaiko is that it comes in several variations. Each type has its own flavor twist, and people definitely have their favorites:
  • Shio mentaiko (salted): This is the most basic version — just lightly salted to let the natural ocean flavor shine through.
  • Karashi mentaiko (spicy): Probably the most popular kind. It’s seasoned with red chili and has a satisfying little kick.
  • Yuzu-flavored mentaiko: Made with Japanese citrus, this one’s refreshing and slightly tangy — perfect if you like a bit of brightness with your umami.
  • Soy or dashi-marinated: A deeper, more savory take that brings out complex flavors with ingredients like soy sauce, sake, or broth.
Each version works best in different dishes — some are perfect on their own, while others shine when mixed into a meal.

How people eat it: traditional and creative ways 🍜🍣

Mentaiko is super versatile. It’s eaten in both traditional and modern ways, and honestly, it works almost anywhere you put it:
  • With steamed rice: One of the simplest and most popular ways to enjoy it. Just warm white rice and a spoonful of mentaiko — comforting and full of flavor.
  • Inside onigiri (rice balls): A favorite grab-and-go snack. Cut open a rice ball and find that salty, spicy surprise inside.
  • As a ramen topping: Especially in Hakata-style tonkotsu ramen, a bit of mentaiko takes the broth to another level.
  • In pasta: Japanese-Italian fusion at its best. Mix mentaiko with butter or cream for a sauce that’s salty, creamy, and slightly spicy.
  • With tamagoyaki (rolled omelet): The sweet egg and the briny roe create a unique contrast that really works.
  • In sushi: Mentaiko shows up in rolls or as a topping, adding both flavor and color.
