Product Details Katsuo Shuto is a traditional Japanese fermented delicacy made from the fresh internal organs (specifically the stomach and intestines) of skipjack tuna (Katsuo).
Extreme Rarity: From a single 4-5 kg skipjack tuna, only 30-40 grams of these specific organs can be harvested, making this a truly premium ingredient.
Production & Taste: Slowly salted and aged over a long period, this careful fermentation process results in a deep, rich flavor packed with natural amino acids and highly concentrated umami.
Usage Suggestions
Drink Pairing (Otsumami): Highly popular as a snack with drinks, especially Japanese sake. The name "Shuto" literally translates to "Liquor Thief"—its savory, salty profile is so delicious it makes you drink your liquor so fast it seems as if it were stolen!
With Rice: Enjoy it simply over a bowl of hot steamed rice or rice porridge (okayu).
Versatile Seasoning (Japanese-Style Anchovy): Thanks to its intense saltiness and deep umami, it can be used as a flavor enhancer similar to anchovies. Stir it into pasta, mix with mayonnaise for a savory dip, or serve it over cream cheese and crackers for an excellent pairing.
