Grapefruit Cookies

These cookies are really amazing, they melt in your mouth!
My mom says : They look like a cloud, they taste like a cloud!"
I've made them many times with lemon instead of grapefruit and now I decided to try something new.
The recipe came from Tina Phan's Blog and I changed it from lemon to grapefruit.

Before baking.

1/2 cup margarine
1/2 cup shortening
3/4 cup sugar
2 tsp grapefruit zest
1/6 cup fresh grapefruit juice
2 cups flour
1 1/2 cup powdered sugar for coating

Preheat oven to 375.
cream margarine and shortening together until smooth.
Add sugar and continue mixing.
Add grapefruit zest and juice and flour in several additions until well blended.
Dough should be easy to work with. 

Prepare cookie sheet with parchment paper on top,
shape dough into small flattened balls each about the size of a tablespoon.

Bake about 10 minutes until edges are slightly browned.
Allow to cool completely before rolling in powdered sugar.

Yum!
