Take the heavy base kadai and transfer the milk into it.
Switch on the stove and heat the milk under medium heat till it comes to boil.
When the milk starts boiling, reduce the flame and continue boiling the milk under low to medium heat by stirring in between at regular intervals.
After about 30 minutes, you will see that the milk has reduced to half. Also the milk starts thickening.
While boiling the milk, layers are formed at the surface and at the sides of the kadai. With the help of spoon remove the layers from the sides and mix it with the milk.
Continue boiling till the milk thickens to turn into malai with semi solid texture. The colour will start changing from white to light yellowish.
At this stage when the milk attains semi solid texture, stir it continuously so that it does not stick to the bottom and sides of the kadai.
Cook the semi-solid milk till all the moisture of the content evaporates and solid milk is formed.
When the milk turns into solid milk, switch off the stove. Khoya is ready to use for preparing different sweets.
Allow the Khoya to cool completely before storing it. Store in freezer to keep it fresh and use for 4-5 days.
