Making your own Nectarine Plum Butter is simple when you follow these steps:

1. Prepare the Fruit: Wash the nectarines and plums thoroughly. Remove the pits and chop the fruit into small pieces.
2. Combine Ingredients: In a large pot, combine the chopped nectarines, plums, granulated sugar, and lemon juice. Stir well to combine.
3. Add Spices: Sprinkle in the ground cinnamon, ground ginger, and salt. Mix until everything is well incorporated.
4. Cook the Mixture: Place the pot over medium heat. Bring the mixture to a simmer, stirring frequently to prevent sticking.
5. Simmer: Reduce the heat to low and let it simmer for about 45 minutes. The fruit should break down and the mixture will thicken.
6. Blend for Smoothness: If you prefer a smoother texture, use an immersion blender to puree the fruit butter to your desired consistency.
7. Add Vanilla: Stir in the vanilla extract, mixing until well combined.
8. Cool the Butter: Remove the pot from heat and let the Nectarine Plum Butter cool for about 30 minutes.
9. Jar the Butter: Transfer the cooled mixture into sterilized jars, sealing them tightly.
10. Store: Store in the refrigerator for up to three weeks or process in a water bath canner for longer shelf life.

These steps will guide you through making this incredible Nectarine Plum Butter effortlessly.
