Pour the reserved liquid from the pineapple cans into a large pot, measuring 1 1/2 cups (top it up with water if necessary). Add the corn syrup and half of the sugar. Stir everything together on medium heat until it all melts. Let it lightly bubble for roughly 4 minutes.
02 -
Turn the heat low and carefully add the pineapple rings, keeping some space between them. Let them bubble gently, flipping often to coat well and prevent sticking to one another.
03 -
Simmer the rings for about 45 minutes, making sure they don’t stick, until they’re no longer cloudy and look see-through.

Lift the pineapple slices out of the syrup and put them on a cooling rack set over parchment paper. Leave them out until completely dry and not tacky to the touch. For quicker drying, pop the rack over a baking pan and place in a 200°F oven for about 30 minutes.

When the rings are fully dry, spread the leftover sugar in a shallow dish. Roll the slices in it until they’re totally covered. Store them in a sealed container at room temperature.
