Wash lemons and dry them very well, Squeeze the juice of 10 lemons. Cut the remaining 40 lemons into pieces, add juice and mix well. Add turmeric and 250 grams salt.
Mix properly and do it for 3 days. After 3 days add 250 grams red chilli powder, garlic paste and methi powder. Mix well and adjust salt and red chilli powder as per taste.
If you have added garlic pods on 1st day, then make a paste from the remaining pods to add on 3rd day.
You can add the chillies at this point. Do not forget to de-seed them. Adjust red chilli powder if required.
If you require more gravy, extra add lemon juice, salt and red chilli powder.
After 3 days refrigerate and enjoy!
