Patty: Kale, mushrooms, yucca, cashews, breadcrumbs, potato starch The Secret: The cheese on top is processed
with katsuobushi, a dried, fermented, and smoked bonito, which adds funkiness
It's made by simmering mirin, rice vinegar,
katsuobushi flakes (from tuna), and seaweed (kombu) over medium heat.
When it reaches a simmer, toss the kombu and add a cup or two
of katsuobushi (a.k.a. bonito flakes a.k.a. dried, fermented, and smoked skipjack tuna).

In between there were pickled french fries, mussels escabèche served in a tin, Manila clams in coconut curry with garlic naan, black cod wrapped in chard, grilled beef tongue, and an omelet made with freshly
shaved katsuobushi dashi.
Umeboshi (salty pickled plums)
with katsuobushi (bonito fish flakes) is a really traditional filling, but you can also use almost anything: teriyaki or soboro chicken, cooked and flaked salmon, or all sorts of maze gohan (mixed rice).
Harvard's Dutton Lab has already partnered with David Chang's world - famous Momofuku test kitchen to study the fermentation of foods like miso, koju and
katsuobushi.
Will definitely have to try this with
some katsuobushi sometime
One suggestion: if you can get ahold of
some katsuobushi (smoked / seasoned tuna flakes), putting some in during the 10 - minute simmer at the end of Step 1 doesn't hurt a bit.
Then came the fun part, adding all the toppings that make this dish quintessentially Japanese: sweet brown Okonomi sauce, Kewpie mayo, powdered nori (aonori), and bonito flakes (
katsuobushi).
I always top mine with «Kewpie» Japanese mayo (sweeter than American), tonkatsu sauce,
katsuobushi, and nori flakes.
Then topped with aonori,
katsuobushi, and Okonomi Sauce.
The liquid is then cooled, strained to remove
the katsuobushi flakes, and finally the juice of one or more of the following citrus fruits is added: yuzu, sudachi, daidai, kabosu, or lemon.
Let the mixture sit for 10 minutes, then strain out the kombu and
katsuobushi.
2 In a bowl mix
the katsuobushi with enough soy sauce so the flakes are a bit wet.
The main ingredients of a dashi are kombu (dried seaweed),
katsuobushi or bonito (dried tuna flakes) and water.
A vegetarian version can be made by omitting
the katsuobushi or substituting it for shitake mushrooms.
