Drain water from rice, wash and grind it with fresh grated coconut , cooked rice and enough water to a medium consistency(adjust with water).
Meanwhile add the yeast to 1 tbsp of warm water and 1/2 tsp sugar, mix well and keep for 5 minutes and then add it to the rice- coconut batter.
keep it overnight at a warm place for fermenting.
Next day add salt and sugar to the fermented batter(you must see the batter bubbled up) and mix it well.
If the batter is thick ,adjust with milk to get the consistency of dosa batter.
Heat an appam kadhai or a deep non-stick tava and grease it lightly with oil/Ghee.
Pour a ladleful of the batter into the Appam Kadai and slowly rotate the kadhai in a circular motion so that a thin layer forms on the sides while the middle remains thick.
Cover and cook for a minute, remove the Vellayappam when the sides starts turning to golden color and the middle fluffy part is cooked.
Repeat for the remaining batter to make to make more appams.
Eat Vellayappam warm with Stew/coconut milk/chicken curry/Kadala curry/Egg curry.
NOTES:
If you do not have cooked rice, take 1 tbsp of row rice flour, and add that to 1/2 cup of boiling water to form a thick liquid and add to the main batter.
Before adding batter to the pan , check if the pan is hot enough by splashing water, once the batter pour to the pan , reduce flame to low.
If you do not have a vellayappam pan, use regular dosa pan.
Pan must be covered with lid immediately after pour the batter and slowly rotate on circular motion.
Vellayappam goes very well with all hot or sweet curries.
