Make sure the khoya you are using is slightly grainy, oily texture, and tastes slightly sweet.
Good quality chocolate like Cadbury Silk chocolate gives a perfect natural chocolate flavor.
Lightly roast the pistachios for enhanced nutty aroma.
When cooking khoya mixture, stir continuously for a smooth and lump-free texture.
After cooking, let the mixture rest at room temperature to thicken it slightly and make it easy to handle.
