Kiwi-Apple Chutney; Canning

I got some locally grown hardy kiwis from a friend with a large hardy kiwi vine, and I decided to make some chutney with the kiwis and some Arkansas Black apples I got from another local grower. I adapted the recipe below from the Ball Complete Book of Home Preserving.

It's okay to adapt ingredients and spices a little bit from a canning recipe, but you can't alter the amount of vinegar in the recipe: that determines the acidity of the batch, and the acidity has to be sufficient to make the recipe safe to can in a boiling water bath. So, I kept the amount of vinegar the same and just altered the ratio of kiwis to apples, and I substituted some balsamic vinegar and white vinegar for the cider vinegar called for in the recipe. (Most vinegar has about the same amount of acidity.) I also substituted chopped butternut squash for the raisins, because I didn't have any raisins. I figured the butternut squash would add some sweetness, as the raisins would have.

Here's what I ended up using. This recipe made five half-pint jars of chutney.

4 cups of chopped kiwis
5 cups of peeled, cored, diced apples
1 1/2 cup chopped onions
3/4 cup white vinegar
3/4 cup balsamic vinegar
1 1/2 cup sugar
3/4 cup dark brown sugar
1/2 cup peeled diced butternut squash
1 large clove of elephant garlic
1 teaspoon peeled diced fresh gingerroot
1 1/2 tsp cinnamon
1 tsp mustard seeds
1/2 tsp cayenne pepper
1/2 tsp ground cloves
1/2 tsp ground allspice
1/4 tsp salt
1/4 tsp black pepper

Combine the kiwi, apple, onions, vinegar, sugar, brown sugar, squash, garlic and gingerroot. Bring to a boil and simmer for thirty minutes. Add the spices, and simmer another ten minutes.

Sterilize the jars and lids. Ladle the chutney into the jars, leaving a 1/4 inch clearance. Wipe the rim with a wet napkin. Put the lids and bands on the jars and place them in the canning kettle. Process for ten minutes at a rolling boil.

Remove the jars and cool on the counter. Check to see that they all sealed.
