I've seen this either when they are trying to sell something to people who don't know better, or in trendy articles written by people who don't care and just write pretty words that are fun to read. Maybe some cultivars/mutations have more fragrance, but even then I myself doubt that it would be much to write home about when comparing it to most other citrus cultivars.
Another one of those, in my opinion, scams, is this shop selling Trifoliate fruits:
https://www.thewasabicompany.co.uk/products/fresh-flying-dragonI quote from the page:
These oranges are rarely eaten raw, instead, they're perfect for cooking. They make wonderful marmalades, syrups and jam and you can also make sweet, chewy snacks by candying the peel with sugar which you can add to cakes and cocktails for a tangy twist.
The rinds can also be a great substitute for lemon zest and used as a cocktail garnish.
Perfect for cooking? Perfect as if there isn't anything much better than this? Not only is there better, this is actually one of the worst.
Wonderful marmalades? If pure trifoliate makes wonderful marmalades, then Yuzu marmalade must blow these peoples panties off with the force of a SpaceX Starship.
Great substitute for lemon zest? That's like saying your garden grass makes a great substitute for lettuce in a salad.
And then they have the balls to ask
€44 per kilo for the fruit. They themselves sell the Yuzu for less.
