Naughty Rhubarb Scones

Slightly modified from Food52
Ingredients:
3 stalks rhubarb
2 1/2 c. flour
1 Tbsp. baking powder
1/2 tsp. salt
8 Tbsp. unsalted butter
1/2 c. vanilla sugar
2/3-3/4 c. heavy cream

Preheat oven to 425.
Slice rhubarb stalks 1/4 " thick. Toss with 3 tablespoons of the sugar.
Sift flour, baking powder and salt together in large bowl or bowl of food processor.
Cut butter into flour mixture by hand (or whiz with food processor) until butter is the size of small peas.
Blend in 1/4 cup of the sugar.
Blend in cream until a soft dough forms. (Note: you may need to add more than 2/3 cup depending on the weather,etc.)
Blend in sliced rhubarb. (If using the food processor, just pulse - you want the slices left mostly intact.)
Transfer dough to floured surface and divide in half. To make triangular scones, flatten into 6-inch disks and cut each circle into 6-8 scones. Sprinkle with remaining sugar.
Arrange on ungreased cookie sheet and bake about 15 minutes or until reddish-brown on top.
Makes 12-16 scones.
