Information about Pomona pectin.
More information about Sugar and Salt-Free Canning in general.
- If using frozen strawberries, zap from frozen in microwave first for 3 minutes. Incorporate any juice that comes off into the mash.
- Don’t crush or mash the berries in a machine, it will damage the pectin.
- You could use canned crushed tomato.
- Pomona pectin comes with a small pouch of powdered calcium for you to mix with water to make calcium water.
- The pectin powder will clump if you just mix it straight in; that’s why you mix it with something first.
- If you are using liquid stevia, how much stevia you need will depend on the tastes of your crowd and how sweet / tart that particular batch of fruit was. Try the indicated amount first, then if you want sweeter add 1/2 teaspoon at a time.
- To use alternative sweeteners such as Splenda, agave, etc, contact Pomona directly to inquire about amounts they would suggest and how to incorporate. It’s almost certainly possible.
