NoodleBomb Shoyu Reserve soy sauce — 7 fl oz bottle
Short answer

Shoyu means Japanese-style soy sauce.

In everyday cooking, shoyu points to a Japanese-style soy sauce profile. It brings salt, aroma, color, and umami, but the best versions feel rounded instead of flat.

NoodleBomb makes two soy sauces: Shoyu Reserve for rich soy depth and Spicy Shoyu for that depth with chili heat. Citrus Shoyu is a separate ramen sauce with a bright citrus finish. Choose by the flavor you want, then start with a little and taste before adding more.
