Drink
Tea
Also called black tea, gunpowder tea, loose tea
Dried leaves of Camellia sinensis. Moroccan mint tea wants a Chinese green, often gunpowder; Irish barmbrack wants a strong black brew to soak the fruit. This is the drink leaf, not matcha powder and not herbal hibiscus.

Origin
China, then a global cupboard. The leaf is the same species whether it is green or black; processing differs.
Flavour
Astringent, floral or malty. Green is grassy; black is malt and dried fruit. Stewed tea tastes of metal.
How it is made
Leaves are withered, then steamed or pan-fired (green) or oxidised and dried (black). Gunpowder green is rolled into pellets. Bags are often broken leaf — faster, rougher.
How to use it
Water just off the boil for green, and do not stew it into medicine — Moroccan mint tea is sweet, repeated, poured from a height. Rolling boil for the black tea that soaks barmbrack fruit overnight; you want strength. Sugar belongs in the Moroccan glass, not in the soaking bowl unless the recipe says so. A second steep of a cheap bag is brown water.
Storage
Airtight, dark, away from spices and coffee. Green fades faster than black. An open box by the kettle tastes of the kitchen.
