I had a lot of sour curds in the fridge, and what else can a Mallu make with sour curds but kuruku kalan. I could also make moru curry or puliserry,but I was feeling nostalgic, and kuruku kalan would be the perfect remedy for my homesickness. In this recipe the curds are cooked and evaporated till it reduces to almost half and can be stored in the refrigerator for a long time. I usually make it with 2 cups of curd, so I have enough evaporated curd to make kalan twice. I learned to make this dish from my mother-in-law, who is from Puthcode. This curry is very different from Moru kootan where raw curds are added to the dish and then cooke. Whereas in kuruku kalan the curd is cooked and exaporated first and then added to the dish and cooked again. This is the traditional way it is made for sadyas, weddings or festivals.
To make the kuruku or evaporated curds
2 cups sour curds
1/2 tsp turmeric
1 tsp black pepper powder
1/4 tsp salt
Kuruku or evaporated curds
Cook this down to 1 cup on medium heat, keep stirring ocassionally. It will look like yellow cottage cheese. Store this in the fridge till you are ready to make the kalan. you could make more kuruku just increase the quantity of sour curds. I sometimes microwave the whole thing it take about 15 minutes. Keep cooking it at 5 minute increments till it reduces to half.
