In north india, we have many variations of kadhi as well i.e. punjabi kadhi, awadhi kadhi, sindhi kadhi, rajasthani kadhi and few variations include combination of vegetables in kadhi recipe. Pakora kadhi and boondi kadhi are also have a special place in every north indian kitchen.I often prepared kadhi with buttermilk, but now a days buttermilk is not easily available. The one available in market is a masala buttermilk which is not a good one to use in this recipe. Now a days i prepare kadhi using curd. The curd should be two days old and kept in refrigerator.
