Yuzu Nr 1

Yuzu Nr 1 comes from the same selection as Yuzu Nr 3, made in the south of France.
Yuzu is cooked in a multitude of ways. Its zest, juice and even albedo (the white part of a citrus fruit) are used in cooked dishes, pastries, ice creams, condiments, etc.
Yuzu jam is without doubt the best citrus jam, with little bitterness and very aromatic.
You can even use the many seeds to sow them, as Yuzu is seed-loyal, 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.
