There are different types of Baghlava or Baklava in the Middle East but the best kind in my point of view id the one which is made in Qazvin.
Qazvin has the most delicious baklava I ever tried in my life. Their baklava sweet is packed with pistachios and almonds and the sugar ration is less than that of Yazd’s. The pastry is thin, which allows you to relish the aroma of cardamom and cinnamon even more.(https://www.parisaspersiankitchen.com)
This famous multi-layered pastry comes in three main variations, known as Pich, Lozineh, and Parchami. Baklava has layers of filo, chopped nuts, and syrup (sometimes honey is used instead of syrup). Qazvini Baklava is so important for the city that some cafes and restaurants, make their own special Baklava.(https://www.tappersia.com)
Besides its price which is much higher than any Persian sweet in Iran and having no rival it is undoubtedly the most delicious Baklava you can have all around the country.
