  • Fresh Blackberries: The fresher, the better! Frozen berries will work too, but you need to let them thaw and you should drain the extra liquid before using them.
  • Sugar: Granulated white sugar (I prefer cane sugar).

6 Tips for Making the Best Homemade Jam

Making your own jam at home can be a great way to save money, enjoy healthy snacks made with organic ingredients and show off your culinary skills. Here are some tips to keep in mind when making your own homemade jam:

  1. Select the ripest fruit available. Ripe fruit will have the most flavor and the least amount of pectin, which is a natural substance that helps thicken jams and jellies. Pectin levels decrease as fruit ripens, so using ripe fruit will result in a jam with better flavor and texture.
  2. Take your time prepping the fruit. Cutting the fruit into small pieces will help it to cook evenly and prevent large chunks of fruit from floating to the top of the jam.
  3. Add enough sugar. Sugar acts as a natural preservative for your homemade jam. It also helps to thicken the jam by drawing out the fruit’s natural juices.
  4. Cook over low heat. Cooking jam over low heat prevents it from burning and making the jam bitter or smokey. 
  5. Skim off the foam. As the blackberry jam cooks, foam will form on the surface. Skimming off the foam will result in a smoother, more flavorful jam.
  6. Can or freeze the jam properly. Jam can be stored in the fridge for up to two weeks or in the freezer for up to one year. To extend its shelf life, you can also can your own jars of jam in a hot water bath.
