Sesame-and-Soy Watermelon Poké

This vibrant sesame-and-soy watermelon poké is a brilliant plant-based alternative to the traditional Hawaiian raw fish dish. By marinating and lightly searing the watermelon, the fruit takes on a remarkably savoury, meaty texture while retaining its refreshing quality. The combination of toasted sesame oil, salty soy sauce, and creamy tahini creates a deeply flavourful glaze that perfectly balances the natural sweetness of the melon.

As a versatile vegan starter or light lunch, this dish is excellent when served over a bed of sushi rice or alongside crunchy cucumber and radish. It is a fantastic option for summer entertaining, as both the watermelon and the umami-rich sauce can be prepared up to 12 hours in advance. Simply garnish with fresh coriander and spring onions for a healthy, homemade bowl that looks as beautiful as it tastes.

Ingredients for Sesame-and-Soy Watermelon Poké

  • 1.4kg seedless watermelon, rind removed, cut into 1-inch pieces

  • 120ml unseasoned rice vinegar

  • 60ml toasted sesame oil

  • 45ml soy sauce

  • 2 tablespoons fresh lime juice

  • 2 tablespoons tahini

  • 1 tablespoon agave nectar

  • 1 tablespoon ume plum vinegar (optional)

  • Kosher salt

  • 2 spring onions, white and pale-green parts, thinly sliced

  • 1 cup coriander leaves with tender stems

Place watermelon in a large resealable plastic bag. Purée rice vinegar, oil, soy sauce, lime juice, tahini, agave nectar, and plum vinegar in a blender until smooth. Pour over watermelon, seal bag, and chill at least 4 hours and up to 1 day.

Heat a large skillet over medium. Remove watermelon from marinade; set marinade aside. Cook watermelon, tossing often, until lightly caramelized and dried out, 6–8 minutes.

Meanwhile, bring reserved marinade to a boil in a small saucepan. Reduce heat; simmer until thickened to the consistency of double cream, 12–15 minutes.

Chill watermelon and sauce separately at least 1 hour.

To serve, toss watermelon with sauce; taste and season with salt as needed. Top with spring onions and coriander.

Watermelon and sauce can be made 12 hours ahead. Keep chilled.
