Start by rinsing the fresh cranberries thoroughly, discarding any damaged ones. Then, chop the pineapple into bite-sized chunks to maximize sweetness and juiciness.

In a medium saucepan, mix the cranberries, pineapple, granulated sugar, orange zest, and fresh lemon juice. Set the heat to medium, stirring gently as the ingredients start to meld together.

Keep stirring while heating the mixture until it simmers. Allow it to cook for about 10 minutes or until the cranberries pop open and create a beautiful, vibrant mixture.

Once simmered, remove the saucepan from heat. Let the relish cool for around 15 minutes; it will thicken further as it cools, enhancing its delightful texture.

Transfer your relish into a serving bowl or jar. You can chill it in the refrigerator if desired before serving to enhance the flavors.
