Umami isn't just one flavor — it's a system. When glutamate (soy sauce), inosinate (oyster sauce), and guanylate (dried shiitake) combine, their effect multiplies. Check off your ingredients and see how your umami stacks up.
Add an inosinate source (oyster sauce, meat) or guanylate (dried shiitake) for synergy amplification — up to 2x the umami impact.
