Quince Jelly

Step 1
Sterilize 8 1/2-pint jars in boiling water for at least 5 minutes, and have new lids ready.

Step 2
Place quinces in a large pot, and pour in water. Bring to a boil, then reduce heat to low; simmer, covered, for 15 minutes. Strain off 4 cups of juice. Mix juice with sugar and lemon juice in a heavy pot, and bring to a boil over high heat, constantly stirring. Stir in pectin, and return to a boil. Boil for 1 full minute, constantly stirring. Remove from heat and skim off foam. Ladle into hot sterile jars, and process for 10 minutes in a hot water bath to seal.

Step 3
Store sealed jars in a cool dark place. Refrigerate jelly after opening.
