I was inspired by http://priyaeasyntastyrecipes.blogspot.in/2011/01/eggless-pear-oats-upside-down-cake.html
I changed the recipe a bit.
Ingredients : 1/4 cup jowar atta,1/4 cup raagi atta,1/4 cup oats,a little less than 1/4 cup maida & another little less than 1/4 cup corn flour,1/2 tsp baking soda,1/2 tsp baking powder,a pinch of salt,1/2-3/4 cup jaggery sugar ( I have given this amount as little more than 1/2 cup was enough for my taste),1/2 cup dahi or curds,1/2 cup boiled water,1/4 cup oil,2tsp vinegar ( I used simple colouless vinegar as I don't have apple cider vinegar).
Method : Mix all the dry flours together in a bowl.Add baking soda ,baking powder & salt to the flour mix & mix nicely with spoon or fork many times.Keep aside.
Mix curds,oil,vinegar & sugar in another bowl..Dissolve sugar so that no lumps of sugar remain.Make aeell in the flour mix & pour the liquid mix of oil,vinegar & curds.Mix nicely.Now add boiled water till no lumps remain & a drop down consistency batter is obtained.Keep aside.
Take a microwaveable vessel & line it with butter paper.Place thinly cut slices of pear on the butter paper in any pattern that you like.Pour the batter over the pear slices.Bake in microwave for 8-9 minutes.My cake came out perfect in 8.5 minutes.
Let it cool in microwave for 10 minutes.Then take out the cake & let it cool for 15 minutes.Then put the microwaveable vessel with cake upside down on to a plate.The cake will drop down on plate.Check if the cake has cooled. Then cut into desired pieces & serve.
My cake was little crumbly -so next time around ,I will put only 1 tbsp of corn atta.
