Made a great umami-mushroom and swiss burger the other day. Mushrooms cooked down with red onion, garlic, worcester, marmite, soy sauce beef stock and brown sugar. Kernel London Stout BBQ sauce on the bun.
So the key taste gimmick of those storied KURO black burgers BK Japan is doing turns out to be a kind of Asian mushroom relish thing. It wasn't enough to ensure a repeat purchase.
Should have stuck some avocado on that bad boy, maybe with a bit of Mayo. Then you would have had a bacon and avo sarnie, which is always a better choice.
