Chamomile, Lavender & Star Anise

a soft evening steep

A hushed, honeyed steep where chamomile's apple-soft calm meets lavender's floral drift, threaded with the sweet licorice warmth of star anise. It is built for the hour the day loosens its grip, a cup that quiets the nerves and coaxes the body toward sleep.

A mellow, faintly sweet terpene alcohol from chamomile that smooths the aroma and lends the cup its gentle, settling character.

FloralCalming

C₁₀H₁₂O
anethole
C₁₀H₁₂O

The warm anise-licorice principle of star anise, rounding the florals with a soft sweetness that keeps the cup comforting rather than sharp.

The film on the tea was never limescale

The film on the tea was never limescale

Water is the most-used ingredient in this index, in twenty-nine of thirty-nine recipes and in every single tea, and it is the one nobody writes down. In the 1990s a chemist at Imperial College spent four papers on the film it leaves on the surface of a cup, and almost everything people assume about that film turned out to be wrong.

Anise is not thirteen times sweeter than sugar, and nobody has ever checked

Sweet taste runs through a single receptor that will accept a sugar, a protein or a synthetic molecule with equal enthusiasm. Which is how anise tastes sweet with no sugar in it. The famous number attached to that fact, though, traces back to an uncited sentence, and the measurement behind it could not have been made.

The spice that fed a drug factory

Star anise was once the world's main industrial source of shikimic acid, the starting material for Tamiflu. It does not follow that star anise treats flu, and there is a poisonous look-alike worth knowing about.
