Peach-Raspberry Jam

I used this recipe, from Sunset magazine.

• 3 1/2 pounds ripe peaches, blanched, peeled, and pitted
• 3 1/2 cups raspberries (1 lb.)
• 1/2 cup lemon juice
• 1/2 teaspoon butter
  
• 1 box (1 3/4 to 2 oz.) dry MCP or Sure-Jell pectin, or 2 boxes (1 3/4 oz. each) dry Ball Fruit Jell pectin
• 10 cups sugar

Preparation

1. Clean and sterilize jars; they say six pint-size jars; I used half-pints and 10 oz. jelly jars.

2. Coarsely chop peaches; you should have 5 1/2 cups. Coarsely chop or mash raspberries; you should have 2 cups.

3. In an 8- to 10-quart pan, combine peaches, raspberries, lemon juice, butter, and pectin. Bring to a rolling boil over high heat, stirring often. Stir in sugar; when mixture resumes boiling, stir for exactly 4 minutes if using MCP pectin (1 minute if using Sure-Jell or Ball Fruit Jell). Remove from heat immediately.

4. Skim and discard any foam from jam.

5. Can leaving 1/4 inch of headspace in each jar and processing jars for 5 minutes.

This recipe is really good. I think I was short on sugar, and used more like 8 cups, which was plenty. It set up nicely with Sure-Jell dry pectin and 1 minute of boiling.
