Hi Anju

I am a Malayalee living in perth. I make very good Appam the recepie is : soak 300 grams of raw rice(not par boiled rice) for 3/4 hours. scrape 1/2 of a cocunut-medium size and grind in a wet grinder or a mixer. Should grind it very fine add one table spoon of sugar and salt to taste. keep it for fermentation. Add yeast(2 to 3 grams) one hour before you need to make the Appam. To make more rich you can add 1/2 cup of coconut milk instead waten while grinding the rice. Make sure you are not keeping the flour in the fridge after adding yeast. Try and send me your experience of making this recepie.
Good luck : Sunitha Sundrem
