There are quite a few different freezer jam recipes out there, some that have the usual jam proportions (i.e., way more sugar than fruit, Certo's freezer jam recipe for example). I prefer the following recipe because it doesn't use so much sugar, and ends up being super tasty no matter what fruit I use.
The Basic Freezer Jam Recipe Proportions are
-4 cups of crushed fruit
-1 to 1.5 cups of sugar
-1 pouch of Bernardin Freezer Jam Pectin
-Lemon/Lime juice and zest
Fortunately, I had four cups of raspberries fall into my lap, so - Raspberry Anise Freezer Jam! I added a teaspoon of anise to the raspberries, and three crushed pink peppercorns, but you could add any herb or spice you think pairs well with whatever 4 cups of fruit you're working with.
