Cut the chicken meat into bite-sized pieces and debone if desired.
Finely chop or press the garlic.
Mix the meat, yogurt, juice of half a lemon, and half of the salt, garlic, pepper, curry, and turmeric well in a bowl. The other half of the salt, garlic, pepper, curry, and turmeric are for the sauce.
Let the marinated chicken rest covered for at least 30 minutes, preferably overnight in the fridge.
