The deep-fried turnover-style pies with the crispy, bubbly crust come in two fairly traditional varieties: Cherry and Apple.
They're being offered at 79 cents a piece but the two for $1 deal has been phased out (at least at my local McDonald's).
According to the company, the pies are available all year long and a rotation of flavors is planned.
McDonald's fried pies were originally discontinued in the US back in 1992 in favor of a baked pie, which was seen as a (slightly) healthier alternative. It was still offered at select locations in the US and at pretty much all McDonald's restaurants in the rest of the world.
(And, yes, I did run out and buy one right away; they ran out of apple though.)
