Strawberry-Kiwi Jam - cooking recipe

Ingredients

3 cups crushed strawberries
3 kiwi fruits, peeled and diced
1 tablespoon minced crystallized ginger
1 (1 3/4 ounce) package powdered pectin
1 tablespoon lemon juice
5 cups sugar
1/2 teaspoon butter

Preparation

Hull the strawberries and crush them one layer at a time (I usually do this with a potato masher in an 8x8 baking dish in about 3 batches.) Peel and dice the kiwi fruits.
Combine the crushed strawberries, diced kiwi, crystallized ginger, powdered pectin and lemon juice in a large stockpot.
Bring to a boil, stirring frequently. Add sugar and butter, stirring until dissolved. Return to a rolling boil and boil hard for 1 minute, stirring constantly.
Remove from heat and ladle the hot jam into hot jars, leaving 1/4 inch headspace. Adjust two-piece caps.
Process for 10 minutes in a boiling-water canner (adjust for altitude).
