Sear the chicken: Heat up 1 tbsp olive oil in a large pot over medium-high heat. Add 12 oz skinless boneless chicken thigh, 1/8 tsp salt, and 1/4 tsp black pepper. Sear the chicken for 5 minutes or until golden-brown on both sides. Transfer to a plate and set aside.

Sauté the vegetables: In the same pot, add the remaining 1 tbsp olive oil, diced 4 oz carrots, 4 oz onions, and 3 tbsp minced garlic. Cook over medium heat for 2 minutes or until the onions are slightly translucent.

Sauté the seasonings: Add 1 tbsp red curry paste, 1 tbsp shallots, 1/2 tbsp lemongrass, 0.5 oz ginger, 0.5 oz galangal, 1/8 tsp ground white pepper, 1/8 tsp cumin powder, 1/2 tsp ground coriander seeds, and 2 tsp curry powder. Stir constantly for 1 minute or until fragrant.

Add broth and simmer: Add the cooked chicken, 3 cups unsalted chicken broth, and 3 tsp brown sugar. Turn the heat up to high and bring to a boil, then simmer uncovered for 15 minutes over medium heat, uncovered.

Mix the thickener: In a small bowl, combine 1/2 cup coconut milk and 1 1/2 tbsp cornstarch. Mix to dissolve.

Add peas and thickener: Bring the heat up to medium. Add 2 oz frozen peas, coconut thickener, 1 tbsp tamarind concentrate, 1/2 tbsp Thai fish sauce, and the remaining 1/8 tsp salt and 1/4 tsp black pepper to the pot. Stir constantly and cook for another minute or until slightly thickened. Turn off the heat.

Serve: Ladle hot curry into a deep dish or a bowl with 3/4 cup warm cooked rice per serving and garnish with 1/4 cup fresh coriander and 0.25 oz red chili peppers.
