Add the blackberries, water and lemon juice to a blender and blend until smooth.
Pour through a sieve to separate the juice from the seeds.
Add 100% pure maple syrup from Canada to the mixture in a small pot, and simmer for 15 minutes.
Remove from the heat and let cool.
Brush a generous amount of marinade on in-season produce and your protein of choice! We love salmon, zucchini and plums.
Grill, roast or bake, then top with a touch more marinade after cooking, while everything is still hot. Enjoy!
