    Let me step back and explain about Mentaiko Pasta in case you are not familiar with this Japanese-Italian fusion pasta.

    Mentaiko Pasta is spaghetti tossed with mentaiko, butter and cream.  I learned that it’s actually pretty popular in some Asian countries but otherwise, either you will have to find a modern Japanese restaurant or you have to fly to Japan to taste this pasta.  In short words, it’s not so common served in typical Japanese restaurants around the world.

    Mentaiko (明太子) is chili-spiced salted roe of pollack or cod and it is usually used as a filling for Onigiri (rice ball).  You can find mentaiko in either refrigerated or frozen section of Japanese supermarkets.

    I did not use colored mentaiko because I want to avoid artificial coloring; therefore, my mentaiko pasta looks less pink/orange.  Also, the spicy level of mentaiko varies depends on mentaiko brand so adjust the spiciness with shichimi Togarashi (Japanese 7-flavor chili pepper) based on your preference.

    If you like calamari, I highly recommend to add it as it gives additional complexities to the dish with different texture and flavor.

    You might wonder if you can skip Japanese mayonnaise (a common brand is Kewpie Mayonnaise); however, I really think this is another must have ingredient.  I know some of you might have a hard time finding Japanese mayonnaise, but try finding it at a Chinese/Asian markets.  They usually carry Japanese mayonnaise (at least around where I live).

    I hope you will enjoy this quick and delicious meal!  It only requires 15 minutes of preparation time!  If you prefer classic Mentaiko Pasta (明太子パスタ), here’s the recipe.

    Recipe Notes

    I did not use colored mentaiko, so my mentaiko pasta looks less pink/orange.

    Japanese mayonnaise: Please use Japanese mayonnaise. The taste of other mayonnaise is not the same. Substitution, click here.

    Udon: Sanuki Udon has more al dente texture and different from typical pre-cooked udon in package. It does not break easily compared to typical udon and it’s more elastic and it has square shape. The texture is more similar to pasta. If you cannot find Sanuki Udon, please use spaghetti or your favorite pasta.
