1-1/2 cups chopped peeled ripe pears
3 tablespoons lemon juice
1 teaspoon ground cinnamon
1/4 teaspoon ground cloves
1/4 teaspoon ground nutmeg
1 package (1-3/4 ounces) powdered fruit pectin
6-1/2 cups sugar
Place first 7 ingredients in a large saucepan; bring to a boil. Reduce heat; simmer, covered, until pears are tender, 15-20 minutes, stirring occasionally. Stir in pectin. Bring to a full rolling boil over high heat, stirring constantly. Stir in sugar; return to a full rolling boil. Boil and stir 1 minute.
Remove from heat; skim off foam. Ladle hot mixture into 8 hot sterilized half-pint jars, leaving 1/4-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. Wipe rims. Center lids on jars; screw on bands until fingertip tight.
