Tenmenjan (甜麺醤) is a rich Japanese sweet bean sauce, essential for authentic East Asian cooking. This version from Ajinomoto's Cook Do line is made from fermented soybeans and flour, delivering a complex, savoury, and slightly sweet flavour with a thick, glossy texture. It is the key ingredient for creating classic dishes like Japanese-style Mapo Tofu or Jajamen noodles, providing the signature taste that defines these popular meals. To use, simply stir-fry it with minced meat and vegetables to create a flavourful base for your favourite weeknight dinner. A small amount adds significant depth and umami to stir-fries, glazes for grilled meats, or as a dipping sauce. This sauce is a staple in Japanese kitchens for quickly preparing hearty and delicious meals.
