Open the pineapple cans and set the rings aside, keeping the juice. You need 1 1/2 cups of juice, so add a bit of water if it's short. Toss the juice into a big pot with half the sugar and all the corn syrup. Heat this up on medium, mixing until the sugar disappears. Let it simmer for around 4 minutes.

Lower the heat, then lay the pineapple rings into the syrup without stacking them. Keep simmering and flip them regularly to stop them from sticking, making sure they're all coated well.

Let everything cook for about 45 minutes. Don't forget to check and stir often so nothing sticks, and cook until the pineapple rings are totally clear.

Take the pineapple slices out of the syrup and place them on a cooling rack with some parchment paper underneath. Let them dry entirely to the point they aren't sticky anymore, which might take overnight. If you're in a hurry, pop the rack over a tray and stick it in the oven at 200°F for around half an hour.

Once they’re all dry, grab the leftover sugar and spread it in a flat bowl. Roll the rings around in the sugar until they’re covered well. Keep them in a tight-sealing container at room temperature when done.
