Preparation

1. For the Amba Sauce: Peel the mangos, cut the flesh of the fruit from the pit, and add it to the bowl of a food processor. Zest the lemons with a grater, reserving the fruit, and add the zest to the food processor. Pulse several times to combine, then increase the speed and process to purée, about 20 seconds.

2. Heat the olive oil in a small sauté pan over medium heat. When hot, add the garlic, mustard seeds, fenugreek seeds, Aleppo pepper, smoked paprika, turmeric, and cumin and cook until the garlic is lightly golden, about 2 to 3 minutes. Add the puréed mango to the pan and stir to combine. Taste and adjust the seasoning by adding salt or lemon juice, as desired. Let the sauce cool, then cover, transfer to the refrigerator, and store, for up to 1 week.

3. For the holishkes: Bring a large pot of salted water to a boil over high heat. Meanwhile, remove and reserve any large, damaged outer leaves from the cabbage head (you’ll use them later in the recipe). Cut out the core of the cabbage with a sharp knife and carefully pull off the rest of the leaves, keeping them whole and as undamaged as possible.

4. Blanch the cabbage leaves in the boiling water for 5 minutes, or until pliable. Run the leaves under cold water to cool them. Carefully cut out the hard center vein of the cabbage leaves so they will be easier to roll up. Take the reserved big outer leaves and lay them on the bottom of a glass or ceramic baking dish, letting part of the leaves hang out the sides of the pan. This insulation will prevent the cabbage rolls from burning on the bottom when baked.

5. Set aside 16 of the best-looking leaves to make the cabbage rolls. Not all of the leaves will be used: just the prettiest ones. Reserve the remainder of the cabbage for a different use (for example: cabbage soup, a stir-fry or lo mein dish, or a slaw).

6. For the Poultry Shawarma Spice: Combine all the ingredients in a small bowl and mix together.

7. To make the mixed grill filling: Preheat the oven to 177°C (350°F). Combine the ground chicken breast, ground chicken hearts, chopped chicken liver, cooked rice, shawarma spice blend, and olive oil in a large bowl and mix well to combine. Place 30 ml (2 tablespoons) of the filling mixture in the center of each cabbage leaf, fold the sides over the filling, and then roll them up. Transfer the rolls, seam-side down, to bottom of a 23×33 cm (9 × 13-inch) glass or ceramic baking dish. Pour enough of the chicken stock around the baking dish to just cover the bottom. Cook the rolls until the filling is cooked through, about 20 minutes.

8. To make the tomato-tahini sauce: While the rolls are in the oven, heat the olive oil in a small sauté pan, add the tomato paste, and fry it just long enough to draw the raw flavor out, about 15 seconds. Add the garlic and a pinch of kosher salt to the bowl of a food processor through the feed tube and process to mince the garlic. Add the nutritional yeast (if using), tahini, tomato paste, and lemon juice to the bowl and process to combine. With the food processor running, add about 237 ml (1 cup) water through the feed tube in a steady stream to form a smooth, creamy sauce approximately the thickness of heavy cream; you may not need all the water. Taste the sauce and adjust the balance of water, salt, and lemon juice as necessary. Turn the tahini sauce out into a bowl.

9. To serve: Using a spatula or palate knife, spread a stripe of the tomato-tahini sauce across each plate. Top the stripe with two holishkes. Garnish with a dollop of the amba sauce in between the two holishkes.
