First make the sugar syrup and allow it to cool completely before baking the cookies.
Add water to sugar and bring it to boil.
Simmer and let it boil for 10 minutes until thick and syrupy.
Set aside to cool.
Preheat oven to 160°C.
In a bowl cream together butter and sugar.
Add the curd and beat until fluffy.
Add the flour, sooji and baking powder.
Make small balls out of the dough and press to make a cookie.
Arrange on a greased baking tray.
Top each cookie with a pistachio nut.
Bake for 20 minutes or until golden.
Arrange the baked cookies on a plate and pour cool syrup on top of each cookie.
After some time the cookie would have absorbed all the syrup.
Serve along with a cup of coffee.
