This marmalade is so simple yet overflowing with flavor. It holds onto the pungent and tart taste of grapefruit but the honey adds a subtle sweetness making this spreadable marmalade a great way to preserve your citrus. It’s delicious with toast and butter or can be used in a variety of savory applications, like as a glaze for duck breasts or on a ham sandwich. You will need a kitchen scale to weigh the ingredients, but the best part of this recipe is that you can make jam from however many grapefruits you have on hand—the other ingredients are portioned accordingly. Marmalade keeps through the winter in the fridge or you can seal sterilized jars in a hot water bath for shelf storage.
