About S&B Foods
S&B Foods (エスビー食品株式会社) was founded 1923 by Minejiro Yamazaki in Asakusa, Tokyo. Yamazaki produced Japan's first commercial domestic curry powder — the "Hidori" brand — and the "S&B" mark (combining "Sun" and "Bird") was added to the trademark in 1931. The flagship Red Can Curry Powder launched 1950, the Golden Curry (ゴールデンカレー) roux range followed, and in 1970 S&B pioneered the tube format for wasabi, karashi, and ginger condiments — now a Japanese kitchen staple.
What's mentaiko
Mentaiko (明太子) is salt-cured pollock or cod roe, traditionally seasoned with chilli pepper — a Hakata (Fukuoka) regional specialty. Bright orange-red, gently salty, with a granular pop in the mouth. Karashi mentaiko is the spiced version; tarako is the milder, non-chilli sibling.
Wafu pasta — Japanese-style pasta
Mentaiko spaghetti belongs to wafu pasta — Japanese-style pasta dishes that pair Italian noodles with Japanese ingredients (cod roe, soy, seaweed, mushrooms, butter). This is a Japanese pasta in its own right, not an Italian sauce reinterpreted.
Flavour profile
Bright pink, savoury, gently spicy. The whole karashi mentaiko grains pop on the tongue against a creamy oil base. Chilli heat is present but not overwhelming — adults appreciate the kick while kids can usually handle it. Pairs beautifully with butter, nori, shiso, or a soft-poached egg on top.
