Take 2 cup water in a vessel and place it on flame for heating. Add 1/2 tsp salt and some turmeric powder into it. When water starts boiling, add aloe vera chunks into it and allow it to simmer for another 6 to 7 minutes.

Take some oil in a pan and heat sufficiently. When oil is hot, add cumin seeds, turmeric powder, coriander powder and green chilly into it and saute on low flame. Now add aloe vera chunks in the spices. Also add salt, fennel powder and mango powder into it and stir constantly. Cook for 3 to 4 minutes.
