"Create a 6-serving Turkish-style etli keşkek that is as light and soft as possible, suitable for someone with gluten sensitivity. Use gluten-free ingredients only, ensure the meat is very well cooked and tender, and keep the texture creamy and gentle. Include imperial units, and make sure the recipe avoids any gluten-containing grains or additives. If needed, suggest a gluten-free grain substitute that preserves the keşkek feel."
