In a saucepan, combine sugar and water. Bring to a gentle boil over medium-high heat.
Once boiling, reduce to medium heat and simmer for 8–10 minutes, stirring occasionally until slightly thickened.
Add lemon juice and honey, simmer for another 2 minutes.
Remove from heat, stir in rose water, and let the syrup cool completely.
Tip: Cool syrup on hot baklava = perfect crisp texture!
Preheat oven to 180°C (350°F).
Grease a 33 cm x 23 cm (13x9 inch) baking tray with melted butter.
Place one sheet of dough in the tray, brush lightly with butter.
Repeat layering and buttering until you have 14 sheets.
In a bowl, mix pistachios, sugar, and cinnamon.
Spread evenly over the 14th buttered layer.
Continue layering the remaining 14 sheets, brushing every second layer with butter (to avoid sogginess).
The final top layer should be buttered.
Using a sharp knife, trim the edges neatly.
Cut the baklava into small diamonds or rectangles before baking.
Drizzle any remaining melted butter evenly over the top.
Bake for 35–40 minutes at 180°C, until deep golden brown and crisp.
Immediately after removing from the oven, pour the cooled syrup evenly over the hot baklava.
Let it soak and cool completely (at least 2 hours) before serving.
Garnish with a pinch of crushed pistachios on top for presentation.
