Prepare the base: In a medium, heavy-bottomed saucepan, combine the orange juice, water, and sugar. Place over a medium heat and stir gently with a wooden spoon until the sugar has completely dissolved. You'll see the liquid turn from cloudy to clear, and you'll hear the gentle hiss of the pan heating up.

Add the aromatics: Stir in the orange zest, cinnamon stick, ground ginger, ground cloves, and the pinch of salt. The fragrance that rises is the first sign of the cosy warmth to come — a blend of sweet spice and citrus that fills the kitchen.

Add the cranberries: Tip in the cranberries and give everything a good stir. The mixture will look thin and the berries will be bobbing around in the syrup. Turn the heat up to high to bring it to a rolling boil. You'll see large, vigorous bubbles breaking the surface.

Listen for the pop: Once boiling, reduce the heat to a steady simmer. After about 5 minutes, you'll hear the first loud pop as a cranberry bursts its skin. This is the signal that the pectin is being released. Continue to simmer, stirring occasionally. The sound will become a gentle, rhythmic chorus of pops and crackles, and the sauce will start to thicken.

Watch for the set: After 10 to 12 minutes of simmering, most of the cranberries will have burst. The sauce will have reduced and will cling to the back of your spoon. To test for doneness, spoon a little onto a cold plate and tilt it. It should slow down and feel syrupy, not runny. The colour will be a deep, rich ruby red.

Finish and cool: Remove the pan from the heat. Stir in the vanilla extract if using. Let the sauce rest in the pan for 5 minutes; you will see it continue to set and thicken as it cools slightly. Remove the cinnamon stick with tongs.

Texture choice: For a perfectly smooth sauce, use an immersion blender to whizz it until it reaches your desired consistency. For a rustic, chunky sauce, leave it as is. I prefer a mix — some whole berries for texture, some broken down for body.

Cool completely: Transfer the sauce to a heatproof bowl or jar and let it cool completely to room temperature. As it cools, it will thicken significantly. You'll notice the glossy sheen settle into a matte, velvety finish.
