Add enough water so that the beetroot strips are soaked in the vinegar solution.
Keep them soaked for 2-3 hours. It is ready to be consumed.
You can use regular vinegar or even apple cider vinegar if you have it.You can reduce chilly powder as per taste. Some people prefer using black pepper instead of chilly powder.You can skip black salt and substitute with regular salt.Adjust salt as per taste.Chopped dill is my addition as I like its taste. It is completely optional.Use the same method to pickle carrots and small onions.
