These scones have the potential to be very good, well they are very good but the recipe told me to greese the cookie sheet and also to cook on 450 F and that resulted in burned bottoms. This recipe calls for lime zest and the lime flavor in the scones is really nice with the blueberries but I don't think there was enough of it. I also don't think there were enough blueberries. I am going to write this recipe for you the way I think it ought to be.
1 1/3 cups flour
2/3 cup cornmeal
3 tbsp white sugar
3 tbsp brown sugar
1 1/2 tsp baking powder
1/4 tsp baking soda
1/3 cup cold butter chopped up
1/2 cup buttermilk
zest of 2 limes
1 1/2 frozen blueberries
1 tsp cornstarch
Preheat oven to 400 F
Make a well in dry mixture, and add the buttermilk mixture all at once.
Stir with a fork until just moistened. Don't over mix.
Toss frozen blueberries with cornstarch, and then add to flour mixture.
Drop dough on floured (not greased) sheet pan in 12 mounds 1 inch apart
The recipe I used also called for a a drizzle made with powdered sugar mixed with lime juice. I did not do this because it just adds more calories, and I have never had a good outcome when making icing with just powdered sugar and a moistening agent. It always tastes icky. I used some honey instead. It was pretty but the honey got all over me every time I ate one. Its really not necessary they are good plain. The recipe also called for sliced almonds sprinkled over the top but again, more calories.
