Raw rice - 2 cups
Fenugreek seeds (uluva/vendiyam/methi) - 1/2 teaspoon
Coconut milk - 1/2 cup ( the readymade coconut milk powder works fine)
Dry Yeast - 1/4 teaspoon
Sugar - 1/4 teaspoon
Salt to taste.
Soak rice and fenugreek seeds for 2-3 hours. Grind to a smooth batter in a mixer bowl. Take 1/2 cup of water and boil till its lightly warm. Dissolve the yeast and the sugar in the luke warm water. Mix the coconut milk, salt and dissolved yeast into the rice batter. Let ferment overnight.
Appams are made in a special shallow kadai called 'appa chatti'. The non-stick variety is available in most stores. Heat the appa chatti and pour in a ladleful of batter. Slightly rotate the appachatti to make the batter swirl creating a lace like crisp outer ring and a thicker middle portion.
In case you don't find an appachatti. Just warm an ordinary dosa pan and pour out the batter. Close it with a lid and simmer till its nicely done. Do not turn over.
