Pectin and Calcium Questions

Stored in the refrigerator, calcium water will last many months. It can be frozen for even longer storage. When you take your jar out of the refrigerator, look at it before shaking it. You should see white powder settled at the bottom and floating near the bottom of the jar, with clear water above that. If you see any colors or mold in the jar, discard the calcium water. Always shake well before using.
