Making Nectarine Fruit Butter is a straightforward process. Follow these simple steps to create your delicious spread:

1. Prepare the Nectarines: Wash and chop the nectarines into small pieces, discarding the pits.

2. Combine Ingredients: In a large saucepan, add the chopped nectarines, sugar, lemon juice, cinnamon, nutmeg, and butter.

3. Cook the Mixture: Place the saucepan over medium heat. Stir gently until the butter melts and the sugar dissolves.

4. Simmer: Bring the mixture to a gentle boil, then reduce the heat to low. Let it simmer for about 30-40 minutes, stirring occasionally. The nectarines should break down and create a thick, buttery consistency.

5. Blend for Smoothness: If you prefer a smoother texture, use an immersion blender to puree the mixture. Alternatively, you can transfer it to a blender and blend until smooth.

6. Add Vanilla: Stir in the vanilla extract if using. This adds an extra depth of flavor.

7. Check Consistency: The fruit butter should be thick and spreadable. If it’s too runny, continue to simmer for a few more minutes.

8. Cool: Remove from heat and let the nectarines cool in the saucepan for about 30 minutes.

9. Store: Transfer the cooled Nectarine Fruit Butter into clean, sterilized jars. Seal tightly and store in the refrigerator.
