Ingredients
- 1(2-inch) square of kombu (dried kelp)
- 2tablespoons bonito flakes (shaved katsuobushi, also called hana-katsuo)
- ½cup shoyu (soy sauce)
- ¼cup freshly squeezed lemon juice (from 1 to 2 lemons)
- ¼cup freshly squeezed lime juice (from 2 to 3 limes)
- ½cup finely diced sweet onion, rinsed and drained well
- 1½teaspoons minced peeled fresh ginger
- 1tablespoon finely chopped fresh shiso (from 2 to 3 leaves)
- 9ounces skinless hamachi (yellowtail) fillet
- Flaky sea salt, such as Maldon
- Extra-virgin olive oil (or lemon olive oil, see Tip)
Preparation
- Step 1
Put the kombu and bonito flakes in a small bowl.
- Step 2
Heat ¼ cup of water until steaming but not boiling. Pour the hot water over the kombu and bonito flakes. Let steep for 15 minutes.
- Step 3
Add the shoyu, lemon juice and lime juice. Mix gently and let the ponzu sit for 2 hours at room temperature.
- Step 4
Strain the ponzu through a fine-mesh sieve and discard the solids. Add the onion, ginger and shiso and mix.
- Step 5
With a very sharp knife, cut the fish straight down or at a slight angle into 16 slices, each about ¼-inch thick.
- Step 6
Transfer the sauce to a chilled plate with a lip, or a shallow serving bowl, making sure to evenly distribute the onions. Shingle the hamachi slices on top. Season the hamachi with some flaky salt and drizzle with olive oil.
- To make lemon oil, gently poach lemon zest in olive oil, then let it steep for about an hour before straining.

Cooking Notes
We had this dish at Tiffany's in Maui few weeks before Christmas...it was fabulous and everything about the restaurant was memorable and nostalgic. I will be making this but just wanted to say thanks for keeping Tiffany's alive and well while reinventing it's menu.
Salty, citrusy, and tart but mellowed by the addition of ginger and onion. I was afraid it would be too assertive but it wasn't, and indeed I enjoyed splashing it on my rice even without the fish. Didn't make the lemon oil, instead drizzled the oil on the fish and zested a bit of lemon peel over it to finish. Delish.
Any reason this ponzu sauce shouldn't be made the day before?
Sure wish the kombu and bonito flakes were in grams.
Question. 2-3 Shiso leaves are not enough to make the sauce that rich red color, is it?
Is the onion raw or cooked wonton a bit?
Is the onion raw or sweated down a bit?
My reading is its raw. This could be why sweet onion is specified.
