- Powder the cashew nuts in a mixer grinder, in small batches. 
- To make this mithai use whole cashews or broken pieces of Kaju. 
- Take care that you do not pulse it for a long time or the cashew nuts would release its oil and it would turn pasty. 
- Sieve the cashew nut powder and keep aside (do not use a fine sieve for this). 
- In a non-stick pan heat sugar and water till the sugar dissolves. 
- Add the cashew nut powder and mix well (there is no need of any string consistency of sugar syrup). 
- Add cardamom powder and stir. Break lumps, if any, while stirring. Keep stirring the mix till it comes together and starts forming a soft dough like consistency. 
- This would take around 8-9 minutes of stirring over medium to low heat. 
- Transfer this lumpy dough to a work surface or on a greased plate. 
- When the dough is still warm (or a bit hot, as long as you can handle it) add 1 tbsp of melted ghee, start kneading it lightly. 
- You may grease your palm with some ghee before kneading. Kneading will smoothen out the dough, do not overdo it. 
- If you find the dough to be hard add a tablespoon of milk and knead to soften it. 
- Flatten this dough with your palm and start rolling it by keeping it in between two parchment papers (butter paper) before rolling it. 
- This would give a smooth texture to the Katli. 
- Ensure that the dough is warm while rolling or it would be difficult to roll the cooled dough. 
- Gently roll the dough to a thickness of 3 to 5 mm. 
- As the katli cools, carefully measure and mark the katli using a scale. Cut it using a sharp knife, in diamond or square shapes. 
- After it cools completely, gently remove the Kaju Katli slices. 
- Serve or transfer the slices to airtight containers and store for further use.
