When I went to Kerala for the first time, Malayalam confused me more than anything. kalan can be many different things.. You eat 'kalan', the other 'kalan' comes to fetch your soul, when you are done with the world, another 'kalan' kuda you use when it rains!. The meaning changes the way you pronounce.. I never got it right. Kalan and olan are essential part of ona sadya..
Chena( elephant yam): 100 gm
Raw green banana(ethakka):1
pepper powder:1 t spn
turmeric powder:1/2 t spn
Ghee:2 tbl spn
Yogurt( thick greek style):1 cup
Coconut (grated) :1 cup
Cumin powder:1/2 t spn
fenugreek(methi) powder:1/2 t spn.( roast the seed and powder)
Mustard seeds:1 t spn
Curry leaves:1 sprig
Dreid red chilli:2, cut in to 1 inch piece
Grind the coconut with cumin powder very well. Try not to add water.
Slice the yam and raw banana in to small pieces(1/2 inch cubes), boil it with 1 cup water,green chillies,salt,pepper and turmeric till the Yam is cooked and there is no more water in the pan. Add a tea spn ghee and mix well.
Add the yogurt to the banana yam mix and cook on low fire, till the mix is thick. Now add the ground coconut, cook till it is boiled and take it off from fire. Sprinkle the fenugreek(uluva) podi on top and gently mix.
Tadka the mustard,curry leaves and the dried Chilli in the remaining ghee and pour over the Kalan
