Ingredients

Instructions

  1. 1Prepare the Mentaiko
    A close-up view of a knife carefully slicing the thin skin of a spicy cod roe piece.

    Place the mentaiko on a cutting board and use a knife to carefully cut open the outer membrane casing.

    Tip: Be gentle to ensure you only cut the casing without crushing the delicate roe inside.
  2. 2Extract the Roe
    The roe being scraped cleanly out of its skin into a bowl with a knife blade.

    Using the back of your knife, scrape the spicy cod roe out from the casing into a small mixing bowl.

    Tip: Hold the casing firmly at one end while scraping to easily remove all the roe.
  3. 3Grate the Garlic
    A clove of garlic being rubbed against a fine metal grater over a bowl.

    Use a hand grater to finely grate two cloves of garlic directly into the bowl containing the mentaiko.

    Tip: Grating garlic creates a smoother sauce consistency than chopping, allowing the flavor to infuse evenly.
  4. 4Combine Sauce Ingredients
    The ingredients being stirred together with a spoon until they form a smooth, creamy, pink-tinted sauce.

    Add the heavy cream, soy sauce, tomato sauce, and half a tablespoon of olive oil into the bowl with the mentaiko and garlic. Stir everything thoroughly until the sauce is well combined.

    Tip: Make sure to break up any large clumps of roe so the sauce is uniform in texture.
  5. 5Boil the Pasta
    Dry spaghetti being dropped into a large pot of bubbling hot water.

    Bring a pot of salted water with a splash of olive oil to a boil. Add the pasta and cook according to the package instructions.

    Tip: Using salted water is essential to season the pasta from the inside out.
  6. 6Warm the Sauce
    The bowl of sauce being heated indirectly over a steaming pot of water.

    Place the bowl containing the mixed sauce over a pot of steaming water (bain-marie). Stir constantly with a spatula for 2 minutes to gently warm the sauce without curdling the cream.

    Tip: Do not let the water underneath reach a hard boil; a gentle simmer is enough to warm the sauce effectively.
  7. 7Drain the pasta
    A metal colander holding cooked pasta, with steam rising.

    Once the pasta has finished boiling, pour it into a colander to drain away the cooking water. Ensure all excess liquid is removed before adding the noodles to the sauce.

    Tip: Drain quickly to keep the pasta from overcooking in the residual heat.
  8. 8Combine pasta and sauce
    Pasta being tossed in a metal bowl with creamy orange mentaiko sauce using a spatula.

    Add the drained pasta directly into the bowl containing the prepared mentaiko sauce. Using a spatula, toss and mix thoroughly until every strand is evenly coated with the creamy, spicy mixture.

    Tip: If the sauce is too thick, add a tablespoon of the pasta water to loosen it up.

Frequently Asked Questions

Tarako (cured cod roe without chili) is the direct substitute. If using tarako, add a pinch of chili flakes to match the original heat profile.
It adds a subtle acidity and depth that cuts through the richness of the heavy cream and balances the oceanic flavor of the cod roe.
If the sauce thickens too much while tossing with the pasta, add a tablespoon of reserved hot pasta water to loosen it to your desired consistency.
