Peach preserve with stevia

The peach tree is a plant of Chinese origin. A legend says that its birth was due to a kernel that a fisherman had found in the belly of a fish and that he had planted in his garden: the fruit was called peach to remember its marine origin. The peach tree was introduced to Italy during the first century. 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.
