Wild London Mushroom Soy Sauce – Fermented Shiitake Umami Sauce. Wild London Mushroom Soy Sauce is made from fermented shiitake mushrooms, traditionally slow-brewed in small batches in Bangkok. There’s no soy, no wheat and no animal products – just mushrooms, koji, time and patience
The result is a deeply savoury, umami-rich sauce with the complexity and everyday usefulness you’d expect from classic soy sauce, but made from something entirely different
So why call it Mushroom Soy Sauce? Because that’s the flavour world it belongs to. It sits somewhere between fish sauce and soy sauce, but closer to soy – the same deep umami and the same pourable, everyday usefulness in cooking
We source it from a small specialist producer in Bangkok who has been perfecting this fermentation for years. It’s the kind of ingredient you find because someone who knows Thai food inside out puts it in your hands and says, try this
Why You’ll Love It. Big on umami – fermented shiitake gives it a deep, savoury flavour
Use it like soy sauce – an easy swap for seasoning, cooking, dipping and drizzling
