What is "turnovers"

Usage examples of "turnovers".

These turnovers were an institution, and the girls called them “muffs”, for they had no others and found the hot pies very comforting to their hands on cold mornings.

They availed themselves of the rare privilege to the fullest extent, for some tried the pleasing experiment of drinking milk while standing on their heads, others lent a charm to leapfrog by eating pie in the pauses of the game, cookies were sown broadcast over the field, and apple turnovers roosted in the trees like a new style of bird.
