I didn't have any bonito or dashi due to local logistics, but it still turned out pretty well. Will need to find a decent Asian market to get those ingredents to make it more "authentically." Definitely will make again. This take about... 45ish minutes to make due to prep work with the onion and garlic.
Perfect fall breakfast brioche is best but didnt have any so thick bread perfect just make sure whatever bread you use leave the slices out over night in the air this way they accept the moister!
