In a large saucepan, combine currants, orange juice, and water. Simmer over medium heat until currants burst and release their juice (about 5–7 minutes).
Use an immersion blender to lightly pulse the jam. Stop blending when you’ve broken down some berries but still have chunks for texture.
If you prefer a smooth jelly, press the mixture through a fine mesh strainer to remove skins and seeds, then return the juice to the pan.
Stir in sugar. Cook over medium heat, stirring often, until sugar dissolves and mixture thickens slightly.
Continue cooking for 10–15 minutes, or until jam reaches your desired thickness. Use the plate test: place a small spoonful on a chilled plate, let it sit for 30 seconds, and push it with your finger—if it wrinkles, it’s ready.
Remove pan from heat. Stir in honey and vanilla. Mix well until combined.
Pour hot jam into sterilized jars, seal immediately, and invert jars for 5 minutes to create a vacuum seal. Cool and store in a cool, dark place. Refrigerate after opening.
Notes
Choose ripe but firm berries – overripe currants can make the jam dull in flavor and color. Don’t skip the plate test – it’s the easiest way to check the set without overcooking.Flavor at the end – if adding vanilla or herbs, stir them in during the last few minutes so they stay fresh and aromatic.Sterilize jars properly – hot jam in hot jars keeps it safe for long-term storage.
