Clean and quarter the pineapple, remove the stalk, remove the pulp from the skin, dice and puree in a blender. Halve the pepper, cut into fine rings and add to the puree.
Bring the puree to the boil in a saucepan and season with apple cider vinegar, honey, curry and salt. Stir the cornstarch with a little cold water until smooth, bring to the boil again, fill the bottles with boiling hot and seal.
