Making nectarine jam may seem like a huge task, but with a few simple steps, you can create a delicious and nutritious jam that will impress your friends and family.
Wash the nectarines thoroughly and remove the pits. Then, chop the nectarines into small pieces. You can leave the skin on or peel it off, depending on your preference.
Place the chopped nectarines in a large pot and add the sugar, lemon juice, and salt. Stir the mixture until the sugar dissolves, and then turn up the heat to medium-high. Bring the mixture to a boil, stirring occasionally.
Once the mixture has reached a boil, add the pectin and stir constantly for 1-2 minutes. Continue to boil the mixture for an additional 2-3 minutes, stirring frequently.
To test if the jam has reached the desired consistency, place a small amount of the mixture onto a chilled plate. Let it cool for a few seconds, and then push your finger through the jam. If the jam wrinkles and holds its shape, it's ready. If not, continue to cook the mixture for another 2-3 minutes and test again.
Once the jam has reached the desired consistency, remove it from the heat and let it cool for a few minutes. Then, carefully pour the jam into sterilized jars and seal them tightly. Let the jars cool completely before storing them.
