Preheat oven to 325˚F (165˚C) with the oven rack in the center. Grease a 9x13 inch (23x33 centimeter) baking dish with an at least 2 inch (5 centimeter) high rim with butter.
Finely chop the walnuts, almonds, and pistachios, either in a food processor or by hand. Do not process into a powder or paste. The nuts should still have a little texture, but not be so large that they tear through the phyllo.
Transfer the finely chopped nuts to a bowl and toss with the ground cinnamon and ground cloves. If you really love cinnamon, add 2 teaspoons or a little more. Otherwise, add 1 1/2 teaspoons and adjust flavors to taste. Set aside.
Place one phyllo sheet on a large work surface, short side facing you. Cover the remainder with a towel to prevent them from drying out.
Brush or lightly drizzle butter over the phyllo sheet.
Top with another phyllo sheet and brush with a little more butter.
Sprinkle the chopped nut mixture evenly over the phyllo in a thin layer.
Optionally, place two wooden skewers or one long thin dowel crosswise over the center of the nut-covered phyllo.
Gently fold the phyllo in half over the skewers, then roll the sheet up, using the skewers as a guide, to form a roll.
Press each end of the phyllo in towards the center to crinkle the roll, then carefully remove the skewers.
Place the crinkled roll seam-side down in the prepared baking dish, either lengthwise or crosswise depending on the length of your phyllo.
Repeat with the remaining sheets and nut mixture until the pan is filled in a single layer of rolls. If there is any nut mixture remaining, set it aside to use as garnish on the finished rolls.
Brush the tops of the rolls with the remaining butter.
Using a sharp knife, cut across the rolls either in thirds or fourths to make individual 2-3 inch (5-8 centimeter) long pieces.
Transfer the baking dish to the preheated oven and bake uncovered until the tops are golden and crisp, 1 hour to 1 hour 15 minutes.
Immediately after removing the baking dish from the oven, slowly pour the cooled syrup evenly over the top.
Set aside at room temperature and allow the Saragli to rest and soak in the syrup, 1-2 hours.
Serve or cover the baking dish once it has cooled and store at room temperature for up to 1-2 weeks.
