Khatta Meetha Nimbu Ka Achar is a tangy and sweet lemon pickle that is popular in Indian cuisine. It is made with lemons, spices, and sugar, giving it a unique and delicious flavor. The lemons are sliced and mixed with a blend of spices like mustard seeds, fenugreek seeds, and turmeric powder. The pickle is then left to marinate for a few days to develop its flavors. This pickle can be enjoyed with rice, roti, or as a condiment with any Indian meal.
