Sweet lemon: Answer: sweet lemons, truth or legend?

Dear Reader,
lemons (citrus limon) are native plants of Asia, rapidly spread first in the Middle East and in Africa, and later throughout the Mediterranean area; these are plants that have been cultivated by man for millennia, so much so that it is not yet clear whether it is a typical species or whether citrus limon is also a hybrid among older plants, also because hybridization between citrus fruits occurs very often and easily. The plants cultivated for the commercial use of the fruits all produce fruits with a very sour taste, because the cultivation of hybrids with thin-skinned fruits, medium-sized, very juicy, rich in citric acid and easy to transport has been particularly developed; therefore the most widespread and most cultivated varieties are not those with the most pleasant-tasting fruits, but rather those that produce fruits that are transported more easily, and wither more slowly. Given that most of the lemon juice produced for the industry is appreciated for its sour taste, the varieties with sweet fruits are not considered valid for the production of commercially interesting fruits.
So the sour fruits of lemons are not unripe, but even if ripe they have a sour taste.
There are varieties of lemons with sweet fruit, light not sweet like a cherry, but sweet like a good tarocco orange, juicy and fragrant, which can be consumed as real fruits, eating the raw and fresh pulp.
The fruits of these varieties of lemon are beautiful, with a thin skin, fragrant and sweet, but often they are not easy to transport, because as happens for example for an apricot, within a short time they deteriorate and become waste. Basically for this reason the plants of sweet lemon they are cultivated only rarely, and their fruits are consumed in the place of cultivation and do not reach all the markets of the peninsula; if you want to take a vacation in Sicily, perhaps you could come into contact with these fruits, and taste them, but it is very unlikely that you could find them at the grocery store or at the supermarket.
Likewise, these citrus fruits do not spread even as ornamental plants, and it is therefore very unlikely to be able to buy a lemon plant that produces sweet fruit.
The only plant that can resemble a sweet lemon, and that can also be found in the nursery, is a hybrid between a variety of lemon and a variety of orange, called citrus meyeri, and produces fruit with the shape and color of lemons, but with a slightly sweeter juice than the common lemons on the market.
