How To Can Strawberry Jam Q&A

What’s the difference between jam, preserves, and jelly?

Jam is my personal favorite.  I like the fruit pieces and the looser, spoon-able texture. With jam, fruit pieces end up in the final product. It’s a mix of solid and liquid.

Preserves contain the most fruit usually in whole pieces and have the least gel-like consistency. Preserves are great for serving with cheese.  Think about spooning an entire berry or cherry on top of your Gorgonzola. 

Jelly is the smoothest of the three and is simply crushed fruit so there are no chunky leftovers, only the fruit juice.  Mixed with pectin, you are left with spreadable, smooth jelly.

The recipe calls for lemon juice.  Is freshly squeezed lemon juice okay to use?

Achieving the right amount of acidity in jam is important. Unfortunately, fruits vary with regard to acidity. Bottled lemon juice has a consistent acidity level and is recommended over fresh for making homemade jam.

Why use pectin in strawberry jam?

Pectin is a soluble fiber so it acts as a thickener.  Fruits and vegetables contain varying amounts of pectin. Strawberries don’t contain a lot of pectic so you will to add some.

You can use Sure-Jell or Ball (which I used for this recipe) to achieve desired results.

Can I use frozen strawberries to make jam?

Yes! Make sure they are thawed out prior to cooking.

Will my jam still work if I reduce the sugar?

Adding sugar to your fruit allows it to set. If you would like to reduce the sugar in your homemade jam using low or no-sugar-needed pectin is the way to go.

These pectins bind with calcium instead of sugar to form the gel. You can cut the sugar in half.

What are some options for serving jam?

Spoon jam on toast, waffles, pancakes, yogurt, and on top of a warm brie crostini.
