Best Apple Pie Jam

We know someone with an over-abundance of apples, and they let us come
and pick a bunch.
I found the yummiest recipe for apple jam and thought I'd post it:

4 cups tart apples, peeled and chopped small
1 1/2 Tablespoons lemon juice
1 teaspoon cinnamon
1/4 teaspoon nutmeg
1/4 teaspoon ginger
4 cups sugar
1 cup packed brown sugar
1 (1.75 oz.) box dry pectin
1 teaspoon butter

1)Measure apples in a measuring bowl, and add enough water to fill to
the 4 cup line (with apples still in bowl)

2)Add pectin, butter, spices and lemon juice

3)Bring to a boil

4)Add sugars and bring back to a full rolling boil. Boil 1 minute

5)Ladle into jars leaving 1//4 inch headspace

6)Process 10 minutes in a hot water bath
