Recipe notes

• 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.
• 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.
• You can reduce the sugar, or use the same volume amount of granulated Splenda®, or 125 ml (1/2 cup / 4 oz) honey or use 1 teaspoon of liquid stevia. For stevia, we’d recommend Better Stevia liquid stevia.
