Step 1

Make the sauce by combining the zest, ginger, honey, cayenne, and salt in a food processor (or use a hand blender) and process until smooth. Add the lemon juice, rice vinegar, and soy suace, and pulse to combine. With the machine running, drizzle in the oils.

Step 2

Slice the watermelon into cubes that are roughly 1/2-inch - 3/4-inch in width. Transfer to a large bowl or container. Pour the sauce over the top of the watermelon and gently toss. Refrigerate for a few hours, or overnight. If you remember to toss the watermelon once or twice along the way, even better.

Step 3

Use a slotted spoon to transfer the watermelon poké to a serving bowl or platter, shaking off extra sauce. Reserve any remaining sauce to use as seasoning (for a poke bowl, or to season rice, etc.). Sprinkle with sliced green onions, and sesame seeds.
