Grease 2 parchment papers lightly with ghee.
Add half of the ghee to a heavy bottom pan (not kadai). Pour water and add sugar, dissolve it on a medium heat.
Turn the heat to low flame and add the almond flour.
Mix well to incorporate the flour into the sugar syrup, making sure to break up any lumps.
Increase the heat to medium and cook stirring constantly until the mixture turns thick, for about 7 minutes.
Add rest of the ghee across the pan and cook for a little longer, for 2 minutes until the almond mixture turns thicker and comes together like a mass. It also leaves the sides of the pan. The whole cooking process takes you around 9 to 10 mins (for 1x & 2x)
Turn off the heat & stir in the cardamom powder. It should look smooth and moist at this stage.
Test if the mixture is ready to set: With a small spoon, take a small portion of the mixture from the center of the pan (not from the edges) and cool down.
Grease your fingers and roll to a ball. It should hold shape and be dry but not sticky. If it is sticky cook for a little longer, another 1 to 2 mins.
Scrape off all the mixture from the spatula using a spoon. Transfer the hot mixture to a greased parchment paper.
Hold the edges of the parchment paper to cover the hot mixture and knead it several times for 2 minutes, until the mixture becomes really smooth. (See the pictures and video). If you feel the mixture is turning dry at the edges, you need to be faster.
You will have a smooth badam burfi mixture. Shape it to a square or rectangle using the parchment paper.
Cover with another parchment paper and roll with a rolling pin to a thin sheet of ⅛ to ¼ inch thickness. If you want you may sprinkle some thin sliced pistachios and roll once more. Or pat the edible silver paper (vark) gently.
Let it cool down a bit and cut with a greased knife to squares or diamonds. For 1x recipe - you will get 9 burfis.
Cool down badam burfi completely before you store it in an air tight container. It keeps good for 7 to 10 days at room temperature and in the refrigerator for a month.
