Green Sichuan pepper is harvested before reaching full maturity. It is therefore more acidic than red, in the same way that a lime will be more lemony and less fruity than a yellow lemon.
Sichuan pepper is actually a "false pepper": its fruits are berries that turn reddish-brown when ripe. They are not very spicy and have a fresh, camphor-like, woody aroma.
Allergens: none (EU Regulation No. 1169/2011)
Understanding the Best Before Date
The best before date (BBD) corresponds to the wording "Best before...". It indicates the period during which the product retains its qualities, particularly its taste and aromas. It is not a use-by date (UBD): a passed best before date does not automatically mean that the product must be thrown away, provided that the packaging is intact and that storage conditions have been respected. However, spices can lose their aromatic intensity over time.
