Steps
Before you start
- Chill the watermelon for at least 1 hour before slicing for the best texture and taste
- Toast the sesame seeds in a dry skillet over medium heat for 2–3 minutes, stirring frequently, then set aside to cool
- Use a sharp knife to cut watermelon and radishes—dull blades crush rather than slice cleanly
Toast the sesame seeds
- Pour 3 tablespoons (30 g) sesame seeds into a dry skillet over medium heat.
- Toast for 2–3 minutes, stirring constantly with a wooden spoon or spatula, until fragrant and golden but not dark brown.
- Transfer to a small plate and let cool completely while you prepare the other components.
- The seeds will crisp up as they cool.

Ready when: Seeds are golden and fragrant, not darkened or smoking
Tip: Watch closely—sesame seeds can burn quickly. If the pan becomes too hot, slide it slightly off heat for a few seconds.
Prepare the ginger dressing
- In a small bowl, combine 3 tablespoons (45 ml) rice vinegar, 1 tablespoon (9 g) minced fresh ginger, 1.5 tablespoons (23 ml) toasted sesame oil, and 0.5 tablespoon (8 ml) honey.
- Whisk vigorously with a fork or whisk for about 1 minute until the honey fully dissolves and the oil and vinegar are emulsified into a smooth, uniform liquid.
- Season with a small pinch of kosher salt to taste.

Ready when: Honey fully dissolved; dressing is smooth and creamy without separated pools of oil
Tip: Whisk from the bottom of the bowl to create an emulsion. If oil separates after sitting, whisk again before using.
Prepare the watermelon
- Cut the chilled watermelon in half, then into quarters.
- Use a sharp knife to remove the rind from each quarter in downward strokes, following the natural curve of the fruit.
- Slice the flesh into 1-inch cubes or thin wedges, discarding any large seeds you encounter.
- You should have about 1.5 lbs (680 g) of prepared fruit.
- Place the watermelon in a large mixing bowl.

Ready when: All rind removed; fruit is cut into uniform 1-inch pieces
Tip: Keep the watermelon chilled right up to serving. A cold, firm watermelon cuts cleanly; a warm one releases more juice and falls apart.
Slice the radishes
- Trim both ends of the watermelon radish or daikon radish with a sharp knife, then peel the thin outer skin with a vegetable peeler or knife.
- Using a mandoline slicer on the thinnest setting, or a very sharp knife held at a low angle, slice the radish into paper-thin rounds or half-moons.
- Aim for slices almost transparent—thin enough to bend slightly without breaking.
- Add the sliced radish to the bowl with the watermelon.

Ready when: Radish slices are translucent or nearly so, bending without shattering
Tip: A mandoline is ideal for even slices, but be careful of your fingertips—use the hand guard or a folded kitchen towel. If using a knife, a gentle rocking motion produces thinner, more uniform slices than pushing straight down.
Dress and toss the salad
- Pour the prepared ginger dressing over the watermelon and radish in the large bowl.
- Using two spoons or your hands (clean hands work best), gently toss the salad for 30–45 seconds, lifting and turning the fruit and vegetables carefully to coat everything evenly with dressing.
- Move slowly to avoid breaking up the watermelon cubes.
- The bowl should have a light coating of dressing and no large pooled puddles at the bottom.

Ready when: All watermelon and radish pieces are evenly coated; no visible dry spots or large pools of dressing
Tip: Toss just enough to coat. Over-handling breaks the watermelon and releases excess juice. If you need to assemble more than a few minutes early, toss the components separately and combine just before serving.
Finish and rest the salad
- Scatter the cooled toasted sesame seeds evenly over the salad.
- If using mint, tear or leave the leaves whole and scatter them across the top; if using scallions, sprinkle the thinly sliced green parts over the salad.
- Season lightly with kosher salt and freshly ground black pepper to taste—start with a small pinch of salt and a few grinds of pepper, then taste and adjust.
- Let the salad sit at room temperature for 5 minutes, undisturbed, so the flavors meld and the salad becomes lightly juicy.

Ready when: Mint and scallion fragrance noticeable; a thin layer of juice visible at the bottom of the bowl
Tip: Add sesame seeds only just before serving so they remain crisp. If making ahead and need to hold the salad longer than 15 minutes, keep the seeds in an airtight container and add them only when ready to serve or eat.
Good to know
Tips
- Watermelon radishes have striped pink and white flesh and mild, slightly sweet flavor; if unavailable, regular red or daikon radishes work just as well and offer more peppery heat.
- Toast sesame seeds in a dry skillet rather than buying pre-toasted—the flavor is fresher and you control the degree of toasting to avoid bitterness.
- This salad pairs beautifully with grilled fish, chicken, or tofu; serve it as a cooling side dish on warm days.
- For extra richness and nuttiness, drizzle a few drops of black or white sesame paste into the dressing before whisking.
Make ahead
Prepare the ginger dressing up to 1 day ahead; store covered in the refrigerator. Toast the sesame seeds up to 3 days ahead and keep in an airtight container at room temperature. Slice the watermelon and radish no more than 4 hours ahead and store separately in airtight containers in the refrigerator. Assemble the salad (steps 5–6) no more than 15 minutes before serving to keep the radish crisp and the watermelon firm.
Storage & reheating
Serve immediately for best texture. Leftover assembled salad (without sesame seeds) keeps in an airtight container in the refrigerator for up to 1 day, though the radish will soften slightly and the watermelon will release more juice. Toasted sesame seeds stay fresh in an airtight container at room temperature for up to 1 week. Do not freeze the assembled salad.
Substitutions
- rice vinegar → champagne vinegar or white wine vinegar. Use the same amount. Both provide bright acidity; white wine vinegar is slightly sharper.
- toasted sesame oil → neutral oil mixed with 0.5 teaspoon sesame oil for less intensity. If you prefer a subtler sesame flavor or don't have toasted sesame oil on hand.
- watermelon radishes (or daikon radish) → thin-sliced jicama or Asian pear. Both offer crunch and sweetness similar to radish but with a milder flavor.
- honey or agave nectar → maple syrup or agave nectar. Use the same amount. All three dissolve easily and balance acidity.
