Pat the shrimp dry with paper towels and season with salt and turmeric.
Heat 1 tablespoon butter in a large skillet over medium-high heat.
Cook shrimp in a single layer until golden on the bottom, about 2 minutes.
Flip and cook until opaque, about 1 minute longer. Transfer to a plate.
Add remaining butter to the skillet along with garlic, shallot, chili, and lemon slices. Cook, stirring often, until lemon is caramelized and tender, about 3 minutes.
Return shrimp to skillet and toss to combine.
Remove from heat and scatter dill over the top.
Serve over steamed rice.
