Ingredients
Method
- Combine 1 quart of watermelon, ginger, onion, garlic, tomato, lime juice, fish sauce, and chili paste into a blender. Blend until smooth and pour into a large bowl. Blend the second quart of watermelon and add to the first batch.
- Place the bowl into the fridge to chill.
- Combine vinegar, water, salt, fish sauce, and sugar into a small saucepan and bring to a rolling boil. If you want to make it spicy, add a teaspoon of the roasted chili paste or chili flakes.
- Add shrimp into the vinegar mixture and turn off the heat. Make sure all of the shrimp is submerged. Set aside for the shrimp to finish cooking.
- Cut off the dry woodsy part of the lemongrass and thinly slice the stalks. Add lemongrass, lime leaves, and oil into a small blender or spice grinder and blend until smooth.
- In a small pan on medium heat, gently fry the oil while continuing to stir until fragrant.
- Strain lemongrass and lime leaf oil through a fine sieve and reserve the oil. Let cool completely.
- Check shrimp to make sure it is completely cooked. Pour shrimp and liquid into a bowl and fill it with ice to stop the cooking process and chill the shrimp.
- Once the ice melts, drain the shrimp. If not serving immediately, cover and refrigerate.
- Right before serving, remove the watermelon soup, cucumber, cilantro, and shrimp from the fridge. Taste the soup and season to taste.
- Ladle watermelon soup into a small bowl and place a small handful of cucumbers and a few shrimp on top. Garnish with cilantro, fried shallots, a teaspoon of the roasted chili paste, and a spoonful of the green oil drizzled on top.
- Serve immediately and enjoy.
Cooking tip: You always want to taste and season food, especially cold dishes, at the temperature you’re going to serve it.
