Ensure the 1 cup cashew nuts are completely dry before grinding. Place in a spice grinder and pulse at 3 second intervals 3-5 times.
You should get uniformly powdered cashew nuts that are slightly moist (due to the natural oils in the nuts) and slightly coarse and crumbly
Do this in smaller batches if needed, do not over crowd the grinder. Once all the cashew nuts are powdered proceed with making the sugar syrup
Place 1/2 cup white sugar and 4 tablespoons water in a non-stick pan on medium heat
Let the mixture boil and then keep stirring until the sugar has completely dissolved and you get a slightly thicker consistency of syrup that coats the back of your spatula (took me around 2-3 mins, so not too long)
Add the powdered cashew nuts and lower heat
Keep stirring continuously for about 8-10 minutes or until the mixture bubbles up and turns into a thick mass that rolls around the spatula as you stir
The mixture may look a bit coarse due to the powdered cashew nuts, do not worry about that
When the mixture starts rolling around and becomes hard to keep stirring, transfer to a plate and add 1 teaspoon ghee
Let it cool down to a point where you can handle the mixture with your fingertips
Knead gently, adding more ghee if you need, mixing in all the crusty and dry parts for about 2 minutes
Do not exert too much pressure when kneading, katlis don’t need the same powerful kneading like rotis do
You should soon have a very smooth dough that’s still warm
Place between two sheets of greasing paper and roll into a circle or square that’s about 1/4″ thick
When still warm, scour with a sharp knife into diamond-shapes
When completely cool, separate the pieces and store in an airtight container in the refrigerator
Kaju Katli keeps well for up to 4 days, we have never had them last beyond that
