Method
Prepare the vegetables. Peel and cube the watermelon, core the tomatoes, peel and seed the cucumber, and peel the aromatics (garlic and shallot).
Combine watermelon, tomatoes, cucumber, shallot, garlic, chili, lime juice, fish sauce, and olive oil in a high-speed blender. Blend on high until completely smooth.
Taste the mixture. It should be a balance of sweet, salty, sour, and spicy. Add a pinch of salt if needed (remember the crab will add some salinity later). For a refined texture, strain through a fine-mesh sieve; otherwise, leave as is.
Transfer the soup to a sealed container and refrigerate for at least 1 hour to allow flavors to meld and the soup to chill thoroughly (aim for 4°C/40°F).
While the soup chills, gently toss the lump crabmeat in a small bowl with a squeeze of lime and a dash of olive oil. Be careful not to break up the lumps.
To serve, pour the chilled soup into bowls. Top generously with the seasoned crabmeat and garnish with fresh mint and cilantro.
Chef's Notes
- Temperature is a crucial ingredient here. Ensure the watermelon is refrigerated before you start blending to reduce the chilling time.
- Quality fish sauce (nam pla) makes a huge difference. Look for brands with few ingredients (just anchovies and salt) for the cleanest flavor.
- If you cannot find good lump crabmeat, poached shrimp or even seared scallops make excellent alternative toppings.
- For an extra elegant presentation, serve this in small glasses as an amuse-bouche shooter.
Storage
Refrigerator: 2 days — Soup may separate; stir well before serving. Store crab separately if possible.
