Instructions
Soak the bamboo skewers in 1 quart of water for 30 minutes; drain and pat dry.
Whisk 0.75 cup coconut milk, 1.5 tbsp palm sugar, 2 tbsp fish sauce, yellow curry powder, ground coriander, ground cumin, ground turmeric, white pepper, minced garlic, chopped lemongrass, and 1 tbsp vegetable oil in a bowl until smooth.
Add the chicken strips to the marinade, toss to coat thoroughly, cover, and refrigerate for at least 4 hours and up to 24 hours.
Make the peanut sauce: In a small saucepan over medium heat, simmer 1 cup coconut milk and red curry paste until fragrant, 1–2 minutes. Stir in the finely ground roasted peanuts, 2 tbsp palm sugar, 1.5 tbsp fish sauce, and tamarind paste; cook, stirring, until the sauce thickens enough to coat the back of a spoon, 4–6 minutes. Stir in up to 0.25 cup water to loosen to a dippable consistency; keep warm or cool and refrigerate.
Make the cucumber relish: In a small saucepan, bring rice vinegar, 0.25 cup water, granulated sugar, and kosher salt to a simmer, stirring to dissolve, 1–2 minutes; let cool 10 minutes. Combine cucumber, shallot, and Thai chiles in a bowl and pour the cooled brine over; let sit 15–30 minutes.
Thread the marinated chicken onto the soaked skewers, accordion-style, dividing evenly.
Preheat a grill or grill pan to medium-high. Brush the grates lightly with 1 tbsp vegetable oil. Grill the skewers 2–3 minutes per side (6–8 minutes total) until lightly charred and the thickest piece registers 165°F.
Rest 3 minutes. Serve the chicken satay with the peanut sauce and cucumber relish; garnish with cilantro and serve with lime wedges.
