Watercress with a Fried Egg and Black Sesame Sauce

Preparation

1. Step 1

   In a medium bowl, mix together the lime juice, a big pinch of salt, and the oil with a fork or a whisk. Add the watercress and toss gently to lightly coat. Divide the dressed watercress among four salad plates and set aside.

   Step 2

   Heat a cast-iron or other heavy skillet that you like to use for eggs over medium-high heat. When it is hot, swirl a small amount of vegetable oil in the pan and crack in the eggs, in batches if necessary. When the edges of the eggs are a bit crispy, the whites are completely set, and the yolks are still runny, transfer an egg to each plate so that it slightly overlaps the watercress. Season the eggs with salt, and drizzle about a tablespoon of the sesame sauce over each portion.

2. Black Sesame Sauce

   Step 3

   Toast the sesame seeds in a small sauté pan over medium heat, tossing frequently, until the seeds become fragrant and begin to pop. Transfer them to a plate and let them cool completely. Grind in 10-second increments in a spice mill or clean coffee grinder to a very fine paste, stirring the mixture, then grinding again, and repeating this process until the paste is completely smooth and glistening from the oil that has been released. This will take 3 to 5 minutes. (If the seeds are not ground into a very smooth paste, the sauce will be gray rather than deep black.) Transfer the paste to a small bowl, add the salt, and gradually whisk in the oil, sake, mirin, and dashi until smooth.
