Blueberry preserve with stevia

Blueberry cultivation was already widespread among Native American tribes, and European colonists learned about its cultivation by bringing this species of fruit to Europe. Only in the twentieth century will we begin to grow blueberries for commercial purposes. We prepare this jam with only fruit, agar-agar (a seaweed) and sweeten it with stevia and erythritol: two natural calorie-free sweeteners. Stevia is a sweet-tasting leaf that was grown 500 years ago in South America. The botanist Pedro Jaime Esteve in the early 1500s, signaled the existence of this honey-flavored plant, but the conquistadors did not attach any importance to the discovery, attracted almost exclusively by the gold of the continent. stevia is about 300 times sweeter than sugar, and, unlike sugar and other sweeteners, it has no nutritional value, i.e. it has zero calories, which makes it the ideal sweetener in the low-calorie diet.
