Sieve plain flour, soda bicarbonate and salt into a bowl.
In another bowl add butter and sugar.
Cream it till it becomes fluffy, creamy and whitish.
Add yogurt, vanilla extract and ginger.
Beat into the sugar butter cream till mixed well.
Add flour mixture and fold into the creamed butter mixture.
Pour the batter over the pear and caramel layer. Spread it out evenly using a spatula.
Bake for 30-35 minutes or till a skewer or cocktail stick inserted in the middle of the cake comes out clean.
Let the cake cool completely in the tin. Don't be in a hurry to remove it.
Using a spatula, run it around the edge of the cake to loosen it a bit.
Using a plate, place it on the cake tin upside down.
Flip the tin and plate over so that the plate is at the bottom and the cake tin on top.
Tap the tin a bit and the cake should come out.If it doesn't flip it over, run the spatula on the edges again.
Once the cake is on the plate, you need to place another one on top, upside down and flip it over. Remove the top plate so the pear layer is shown on the top.
Serve with some tea or coffee or serve with ice cream as dessert.
