Yuzu Nr 1

Yuzu Nr 1 comes from the same selection as Yuzu Nr 3, made in the south of France a few decades ago.
Yuzu is cooked in many different ways. Its peel, juice, and even the albedo (the white part of a citrus fruit) are used in cooked dishes, pastries, ice creams, condiments, etc.
Yuzu jam is probably the best citrus jam, without bitterness and very aromatic.
You can even use the many seeds to sow them, as Yuzu is true to seed, unlike almost all citrus fruits (whose seeds are 80% hybrid).

The fruit is slightly smaller than that of Yuzu Nr 3 but contains fewer seeds.
Harvesting begins in October, about two weeks before Yuzu Nr3 .

The tree is vigorous, very thorny and very productive.
