Prepare the Fruit Base : In a separate small bowl, combine the mixed berries and lemon juice. Gently press on about half of the berries with the back of a fork to release their juices, creating a quick, textured compote.
Infuse the Yogurt Cream : In the medium mixing bowl, whisk together the low-fat Greek yogurt, chia seeds, maple syrup, vanilla extract, and ground cardamom until the mixture is smooth and uniform.
Allow Seeds to Bloom : Let the yogurt mixture rest for about 5 minutes. This gives the chia seeds a head start in absorbing moisture, which will create a thicker, more pudding-like consistency.
Layer the Parfaits : Divide the crushed berry mixture evenly among the three glass jars, creating the bottom layer.
Add the Yogurt Layer : Carefully spoon the prepared yogurt cream on top of the fruit base in each jar, spreading it to the edges to create a clean, distinct layer.
Chill for Texture : Seal the jars and place them in the refrigerator for a minimum of 20 minutes to allow the flavors to meld and the chia seeds to fully soften. For an ideal texture, chill for at least 4 hours or overnight.
