Step 1

Preheat oven to 400 F

Step 2

In a medium bowl mix yogurt, garlic, lemon juice and salt. Sprinkle mint or basil on top (optional) Keep in fridge until ready to serve.

Step 3

Season chicken on both sides with 1 teaspoon salt and a few grinds of pepper. Heat 2 tablespoons oil in large skillet over medium heat until very hot. Add chicken – it should sizzle – and cook 6 minutes per side, or until no longer pink. (It will be golden brown on the outside and tender and juicy on the inside) Remove from heat, cut into bite-sized cubes and set aside. Add 1 tablespoon oil to skillet, add onions, 1/2 teaspoon salt, turmeric and a few grinds of pepper. Cook, stirring occasionally, 6-7 minutes over medium heat until onions soften and turn golden brown. Mix with cubed chicken and set aside.

Step 4

Put rinsed rice and 1 teaspoon salt in a medium saucepan and add water to cover by 2 inches. Bring to a boil, lower heat and cook, covered, for 7 minutes. Pour into a strainer, drain, rinse with cold water to stop cooking and set aside.

Step 5

Whisk egg yolks, yogurt, saffron, 1/2 teaspoon salt and a few grinds of pepper in a medium bowl. Add half the cooked, drained rice, mix thoroughly and set aside.

Step 6

Swirl melted butter and olive oil in the 2-quart casserole to coat bottom and sides. Add yogurt & rice mixture and smooth it out into an even layer with the back of a spoon. Add chicken and onion mixture next, making an even layer. Add 1 teaspoon olive oil and 1/2 teaspoon salt to the remaining plain white rice, stir to combine and add to top of casserole, pressing it down gently. Cover casserole with lid or a double layer of foil and bake in the lower third of preheated oven for 45-50 minutes, until a light brown crust forms on the bottom. Remove from oven. Carefully flip casserole upside down onto a platter. Cover the top with a clean dish cloth while you give the Barberries a 1 minute stir in a frying pan with a bit of oil. Toss them on top of the Tachin to garnish. Cut Tachin into six servings and enjoy with yogurt sauce on the side.
