Take 1/4 cup of milk in a glass and add 1 tbsp lemon juice in it. Mix and keep aside to curdle for 10 minutes.
Add 50 gram butter and 1/2 cup powdered sugar in a bowl.
Whisk them until they are combined well and butter turns creamy.
Add 2 tbsp lemon juice, 1 tbsp lemon Zest, few drops of yellow food colour and milk (in which lemon juice was mixed recently).
Whisk again well.
Now add 1 cup flour, 1 tsp baking powder, 1/4 tsp baking soda, 1/4 tsp baking and 1/4 tsp Salt.
Mix them well into a dough using your hand.
Now scoop out the dough (we used ice cream scooper) and keep on placing in a plate.
Roll each scoop into a ball.
Toss each ball into powdered sugar.
Arrange all the sugar coated balls in a plate.
Keep the plate in refrigerator for 15 minutes.
After 15 minutes, again coat all the balls in powdered sugar for the second time.
Arrange all balls in a baking tray lined with greased butter paper and slightly flatten them.
Bake in a pre-heated oven @180°C for 18-20 minutes in the middle rack with both the rods on.
Take the tray out and let the cookies remain in tray for 10 minutes.
After 10 minutes, transfer the cookies from tray to cooling rack and let them cool completely.
