Chia seeds are small, black or white seeds derived from the Salvia hispanica plant, which is native to Mexico. They are packed with nutrients and considered a superfood due to their numerous health benefits.
Chia seeds are rich in fiber, omega-3 fatty acids, protein, and various essential minerals. They can help improve digestion, promote heart health, manage blood sugar levels, and support weight loss.

Chia seeds, in my opinion, have no real taste.  I personally add them on salads, mix them in with my everything bagel seasoning, and add it to yogurt and smoothies when I make them.  I’ve also added them to stews and my easy healthy turkey chili and my healthy coleslaw

Chia seeds can be eaten dry, but soaking them in water or another liquid for a few minutes forms a gel-like consistency, making them easier to digest and releasing more nutrients. In this recipe, you are adding them to wet ingredients so you are getting all those nutrients.
Chia seeds are naturally gluten-free and can be a valuable addition to gluten-free diets. They are also suitable for vegetarians and vegans, serving as an alternative to animal-based sources of omega-3 fatty acids. And that’s why I like to add them to many of my recipes and meal. Since there is little to no taste, I treat chia seeds like a condiment.
I can get chia seeds right at my grocery store now. I find them in the same aisle as flour and sugar. I use to find it in the produce department so ask at your store. You can also get them at Trader Joe’s, Whole Foods and Sprouts.

Reduce the heat once it comes to a boil and simmer uncovered for 10 minutes until the jam thickens.  Remove from the heat and let cool a bit before ladling the jam into the jars.

You can see how the chia seeds have thickened up the jam without any other thickener or additional sugar products.  So, besides being delicious, it is also really good for you. 

This recipe can easily be doubled or tripled.  Just multiply the ingredients equally.

I often get asked if you can substitute frozen raspberries.  Yes, absolutely.  But, if you have fresh, definitely use them since you’ll have more texture and, of course, the flavor can’t be beat.

You could also use other berries like strawberries and blackberries.
