Firstly, in a clay pot take 2 cup leftover rice and break lumps with your hand. Make sure to prepare this at night, and have the ganji for morning breakfast.
Now add 1 cup hot water, 1 cup milk and mix well.
When the mixture is slightly warm, add ½ tsp curd and mix well.
Top with ½ onion, 3 chilli and cover.
Allow to ferment overnight or at least 8 hours.
The next morning, the curd has set well. Mix gently and the fermented curd rice is ready to serve.
Do not forget to add salt and pickles while serving Ganji Annam or Chaddannam.
