Mentaiko is marinated pollock roe and a popular ingredient in Japanese cuisine. Using it to make mentaiko pasta (明太子パスタ) is my favourite way to enjoy this ingredient. This Italian-Japanese pasta is usually quite expensive on the menu, but easily less than half the price and more than double the roe, to make at home.
As gourmet as this pasta may sound and look, it is actual the simplest pasta recipe out there! The sauce does not require stove-top cooking and took me 5 minutes. The only real cooking I did was to cook the pasta (spaghetti).
To make the 5-minute sauce, I basically melted butter in the microwave, then whisked in the other ingredients in a small bowl.
There are two main types of spicy ‘karashi’ mentaiko (辛子明太子) you can find at the local Japanese supermarkets. The colourless type will result in a colourless pasta with visible bits of roe in it. On the other hand, the coloured type (featured in this recipe; pictured above), will result in a slight salmon pink pasta sauce. Click here to read more information about mentaiko.
Using colorless mentaiko will result in a pale pasta while using the coloured type will result in a pale salmon pink sauce. Be sure to buy the right type of mentaiko accordingly to your preference.
If you prefer a richer taste, you can add 1 tablespoon of cream (to taste) to the mentaiko sauce.
