Is it possible to process this jam in a waterbath canner to preserve for longer period of time?

John

Note that you won't get the omega-3 benefit of the chia seeds if you don't grind them first! Yes it's really true. Search the nutritionfacts site of Dr. Greger.

Donna

Can I use frozen fruit as fresh isn’t always available?

Lisa, Forks Over Knives Support

Hi Donna, While we haven't tested this recipe with frozen fruit, we think it's likely to work fine. Be prepared to simmer the berries for a bit longer until they're thick. Let us know how it goes!

Joyce

Although I made a smaller batch it great.

Karyn M

Is there a substitute for the maple syrup in this recipe? 1/2 cup of maple syrup has 90 grams of sugar. That's over 22 teaspoons! Even though maple syrup has some vitamins, it's not worth the huge amount of fructose.

I would use date syrup or whole dates.
