01 - Preheat oven to 340°F. Grease a 9x13-inch baking dish with a little melted butter.
02 - Combine walnuts, pistachios, almonds, cinnamon, cloves, and sugar in a bowl. Mix thoroughly until evenly distributed.
03 - Unroll phyllo dough and cover with a lightly damp cloth to prevent drying while working.
04 - Place one phyllo sheet in the dish, brush lightly with melted butter. Repeat with 7 more sheets, buttering each layer (total 8 sheets).
05 - Sprinkle 1/3 of the nut mixture evenly over the buttered phyllo base.
06 - Add 4 more phyllo sheets, buttering each. Sprinkle another 1/3 of nuts. Repeat with 4 more buttered sheets and remaining nuts.
07 - Layer remaining 4 phyllo sheets, buttering each. Brush the top generously with butter.
08 - Using a sharp knife, cut the assembled baklava into diamond or square shapes before baking.
09 - Bake for 45-50 minutes until golden brown and crisp throughout.
10 - While baklava bakes, combine sugar, water, honey, cinnamon stick, and lemon peel in a saucepan. Bring to boil, then simmer 10 minutes. Cool slightly and discard cinnamon stick and peel.
11 - Immediately remove baklava from oven and slowly pour warm syrup evenly over the surface. Allow to cool completely before serving.
