For the chenna
Combine the cow’s milk and buffalo’s milk in a broad and deep non-stick pan and bring to a boil.
Switch of the flame and wait for 1 minute, while stirring occasionally.
Add the lemon juice gradually and keep stirring gently.
Allow it to stand for ½ minute to curdle. It is completely curdled, when the chenna and the whey (greenish water) separate out.
Strain using a muslin cloth. Discard or store the whey.
Place the muslin cloth with the chenna in a bowl of fresh water and wash it 2 to 3 times.
Tie and hang for 30 minutes for the extra water to drain out.
How to proceed
Put 1 cup of water in a steamer or a pressure cooker, add the 1/2 cup of sugar and bring to a boil, while stirring occasionally so that the sugar dissolves completely.
Meanwhile, squeeze the muslin cloth to drain any more water remaining.
Place the muslin cloth on a flat plate, open it and knead the chenna very well using your palms for 3 to 4 minutes or till the chenna is smooth and free of lumps.
Divide the chenna into equal portions and roll each portion into small balls between your palms.
Put the chenna balls into the sugar water and cover and steam for 7 to 8 minutes.
Switch off the flame and allow it to stand in the steamer for 10 to 15 minutes.
Remove gently into a bowl, refrigerate and serve chilled.
