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.

How to make Sesame-and-Soy Watermelon Poké
Back to contentsPlace 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.
