Place a small plate in the freezer for later use.
Remove the pit from the peach.
Weigh the peach on a kitchen scale.
Weight out equal amount of strawberries.
Remove the top from the strawberries.
Place the strawberries and peach into a food processor.
Using the pulse button, chop the fruit until the pieces are small, but not completely pureed.
In a large bowl, weight out enough sugar to equal the same weight of the peach and strawberries combined.
Add the fruit on top of the sugar and mix well to combine.
Add the pectin.
Heat a frying pan or skillet over high heat.
Add the fruit and sugar mix to the pan.
Stir regularly until the jam starts to thicken. Remove the heat.
Put a small amount of the jam on the plate you put in the freezer. Put back in the freezer and wait for 1-2 minutes.
If the jam is set, it won't hardly move if you turn the plate on it's side. If the jam easily runs down the plate, you need to cook it longer.
When jam is done, place into a jar and into your fridge or freezer. This jam is not mean to be canned or left at room temperature.
