Preheat oven to 375º
Line baking sheet with parchment paper
Combine four, baking powder, salt and sugar in
a food processor, pulse a few times to combine.
ADD the shortening and rosemary, pulse long
enough to form pea size pieces, then add the
half and half, pulse just long enough to form a dough
that pulls away from the sides of the processor.
Lightly flour the work space. Transfer dough,
rolling it out to about 8 inches wide by 9 inches long.
Use a sharp knife to cut into 16 square biscuits.
