Acid from citrus, umami from soy and seaweed along with the smoky goodness of bonito… Yes, you need to make this. I originally used it on black cod, but it didn’t look pretty enough. It is absolutely stellar on steak!
Time: 10 minutes (plus steeping time)
250g brewed soy sauce (or coconut aminos)
150g fresh lemon juice (approximately four large lemons)
75g fresh lime juice (approximately two large limes)
60g rice vinegar
10g piece kombu
10g bonito flakes
0.5g cayenne pepper
Combine all ingredients in a mason jar or other suitable container.
Cover and refrigerate for twenty-four to forty-eight hours.
Strain through a fine mesh sieve or coffee filter.
Serve immediately or refrigerate for up to four weeks.
