It’s not what it looks like.
No, it’s not a poorly timed April Fool’s prank and no, I have not begun eating fish (perish the thought!) What you’re looking at is in fact good old fashioned watermelon, dressed up like ahi poke, the highly prized Hawaiian delicacy. Rather than mere eye candy, believe it or not, these ruby red cubes really do taste quite fishy- And in a good way! What really seals the deal is the texture, no longer bearing the crisp bite that you would want for an average melon, but meaty and downright silky on the tongue.
The concept for watermelon-based tuna is one that I heard of many years back, created with the aid of a chamber vacuum sealer to compress the melon flesh while simultaneously infusing new flavors. Lacking such expensive equipment, the idea languished in the back of my head, until a surplus of the sweet summer fruit prompted me to go beyond standard preparations. Turns out that it only takes a simple freeze and thaw cycle to transform fresh produce into something of a more oceanic nature. This is one that requires nice firm watermelon to start with, so don’t wait until the season ends and only mealy melons remain. Act now, and keep the “fish” stashed in the freezer until you’re ready to enjoy up to four months later.
Not only does it make an unbeatable poke bowl, but it’s perfectly suited to just about any other raw preparation you can imagine, such as tuna tartare. A perfectly savory appetizer deserving a place at even the fanciest affair, this mustard- and caper-spiked combination pairs well with crackers, plain, seeded, or herbed. Really, the sky’s the limit, as I enjoyed mine on top of leafy green salads as well.
Creating a delicious vegan fish alternative has long been the final frontier for meatless cooking, and I believe this brings us all one giant leap closer to that holy grail.
Fish-Free Watermelon Tuna
1 Cup Mushroom Broth
4 Tablespoons Reduced-Sodium Tamari
2 Tablespoons Olive or Sauerkraut Brine
1 Tablespoon Rice Vinegar
1 Tablespoon Chickpea Miso Paste or White Miso Paste
1 Small Clove Garlic, Finely Minced
2 Sheets Nori
1 1/2 Pounds Cubed Seedless Watermelon
In a large, shallow container, whisk together the mushroom broth, tamari, brine, vinegar, miso paste, and minced garlic. Place the cubes of watermelon into the marinade so that all of the pieces are covered, ideally in a single layer. Arrange the sheets of nori so that they cover the melon and make contact with at least one side of all the pieces. You may need to move things around so that you have a sheet of nori at the bottom of the container and one on top to achieve this layout.
Cover with plastic wrap and place the container on a flat surface in your freezer. Allow the whole thing to fully freeze; at least 12 hours, but ideally 24 or longer. If you want to save the “tuna” for a later date, just leave it at this stage until you’re ready to serve it. To continue preparing your fish-free feast, allow the tuna to fully thaw either in the fridge or at room temperature. Remove and discard the wet nori, and drain away the excess marinade. You can save this and reuse it if you like, since there’s no potential bacterial contamination like you would get if using raw meat. Your watermelon tuna is now ready to eat or use in other recipes!
1 Batch Fish-Free Watermelon Tuna (Above)
2 Scallions, Thinly Sliced
1 Tablespoon Reduced-Sodium Tamari
1 Teaspoon Toasted Sesame Oil
1/2 Teaspoon Crushed Red Pepper Flakes
Fresh Limu or Rehydrated Arame, to Taste (Optional)
1 Batch Fish-Free Watermelon Tuna (Above)
2 Teaspoons Brined Capers, Drained and Rinsed
1 Teaspoon Dijon Mustard
2 Tablespoons Finely Chopped Shallot
2 Tablespoons Finely Chopped Parsley
4 Teaspoons Olive Oil
For either the ahi poke or tuna tartare options, simply mix all of the ingredients together and gently toss in the “tuna” to combine. Let marinate in the fridge for up to a day, but at least one hour before serving. Top freshly cooked, hot white rice with the ahi poke to make a classic poke bowl, and finish with sesame seeds if desired. The tartare can be served up plain, with crackers, or tossed with salad greens.
