Measure crushed peaches into a bowl and stir in the lemon juice. Add sugar. Add the pectin to the bottom of the Jam Maker with the Stirrer in place. Pour the crushed peaches and lemon juice evenly on top of the pectin.
Add the margarine.
Split the vanilla beans in half and scrape each half of the bean(s). Put the vanilla pods and scrapped beans into the Jam Maker. Run the Jam & Jelly Maker for 4 minutes until you hear 4 short beeps. Slowly add the sugar.
Allow the Jam Maker to run for the remaining 18 minutes on the timer undisturbed. When the Jam Maker beeps again the jam is done. Carefully remove the lid. Place it on a towel out of the way.
Fill your jars leaving the vanilla bean(s) in the jam. Process the jam in a hot water bath for 20 minutes. Remove jars after five minutes. Allow the jars to cool for 24 hours. Check for a proper seal before storing.
