Justin Chapple’s simple panna cotta is the perfect smooth, creamy summer dessert. The cool tang of buttermilk pairs perfectly with sweet, ripe mango. To easily peel mango, cut off the mango cheeks and discard the pit. With one hand, hold a thick pint glass firmly on a work surface. With the other hand, place one mango cheek on the rim of the glass where fruit meets the skin of the mango. With gentle pressure, push mango cheek down the side of the glass so the flesh falls into the glass and the skin remains in your hand. Repeat with the second mango cheek.
