For a richer flavor, use high-quality European butter. Be gentle when working with the phyllo dough, as it can tear easily. Keep the stack of phyllo covered with a damp towel to prevent it from drying out while you are working. Ensure the syrup is hot when you pour it over the baklava for maximum absorption. Adjust the baking time slightly depending on your oven; the baklava should be deeply golden brown. If the top is browning too quickly, tent it loosely with foil during the last 15 minutes of baking.
