Step 1

Toss chicken with 2 tsp of fish sauce, then add a little vegetable oil and toss to coat—this is just to help the chicken spread more easily in the wok, and it also helps keep the moisture in while you sear. Let chicken marinate while you prep other ingredients, about 15 minutes.

Step 2

Cut the salted duck eggs right through the shell in half, then use a spoon to scoop the halves out. You can cut each half into chunks and toss them into the stir-fry, or serve on the side like I did in the video. Note: If you want to toss it into the stir-fry, only use 1 egg, and you can always have more on the side.

Step 3

In a wok or a large saute pan, add just enough vegetable oil to coat the bottom and heat over high heat until the pan is very hot. Add just enough chicken so they're not crowding in the pan (I do this in 2 batches), spread the pieces apart and sear without stirring until browned, about 1 minute. Once browned, stir the chicken briefly just to cook the surface of the other side, and then remove from the pan—the chicken should only be partially cooked at this point. Repeat with the remaining chicken.

Step 4

Let the pan cool a bit, then with the heat off, add about 2 Tbsp of vegetable oil and the curry paste. Stir the curry paste in the oil until it's loosened, then turn the heat on to medium. Cook the curry paste, stirring constantly, until it is thickened.

Step 5

Stir in the palm sugar, fish sauce (start with 1 tsp if you're not sure how salty the curry paste is), and deglaze with 1/4 cup of chicken stock. Keep stirring until the sugar is mostly dissolved, deglazing with more stock as needed if it starts to stick to the pan.

Step 6

Add the torn kaffir lime leaves and let them infuse into the sauce for about 30 seconds.

Step 7

If the sauce looks thick, add a little more chicken stock to get it into an pourable consistency. Add the partially cooked chicken and toss just to coat in the sauce. Add the long beans and cook until the chicken is fully cooked and the sauce is no longer pooling and the curry paste is coating the chicken and the beans. If you want to add the salted duck egg chunks into the stir-fry, toss them in at this point and stir just to mix.

Step 8

Remove from heat and transfer to a plate. Garnish with finely julienned kaffir lime leaves, and place the salted duck eggs on the side. Serve with jasmine rice, and enjoy!
