Preheat oven to 450 F and grease a cookie sheet. Rehydrate apples in apple juice for at least 5 minutes. Drain well.
Combine flour, baking powder, soda and salt in a large bowl. Cut in 76 g
butter until small particles are formed. Add milk. Stir with a fork
only until dough holds together. Form dough into a ball with floured
hands. Knead lightly about 10 or 12 times with fingertips, on a floured
surface.
Roll out dough to form a 10” x 12” rectangle. Brush dough with the
remaining butter, softened. Spread diced apples over dough; sprinkle
with sugar and cinnamon. From the long side, roll up the dough, pressing
edge down to seal. Cut into twelve 1-inch slices. Lay slices on a
greased cookie sheet, spacing them an inch apart. Bake 10 to 12 minutes,
or until nicely browned.
