fennel seeds

Foeniculum vulgare, and what looks like a seed is a whole dry fruit, a schizocarp built to split into two ridged, oil-striped halves, the same construction as its Apiaceae relatives cumin, coriander, anise, and caraway. Seven recipes in this library use it across three kitchens: four teas, two spice mixes, and a batch of digestive gummies. Deep Sleep Tea simmers 0.4 grams of it alone for three minutes before the heat comes off and the chamomile, lavender, valerian, and mint go in, the exact staged method the site's own note on brewing traces across this library. Low Tide (2 grams) and Sweet Digestive Tea (0.25 grams) simmer it together with ginger, licorice, and other hard ingredients before the delicate herbs follow, and Gentle Gas Relief Tea uses a bare 0.1 grams the same way. Fish Spice Mix (1 gram) and Japanese Curry Powder (2 grams) toast it whole in a dry pan before grinding it into the finished blend, and the Carminative Digestive Gummies steep 2 grams of the seed into the tea base that later gets set with agar.

The seed's sweetness is trans-anethole, the same molecule anise and star anise carry, dominant enough in fennel oil that, as the curry powder's own recipe notes put it, fennel and anise are two different plants pushing the same molecule, so they read as one flavor. It reaches the same sweet receptor, T1R2/T1R3, that every sugar activates, so a pot built with no sugar at all, like Sweet Digestive Tea's fennel-anise-cumin base, still tastes confectionery, though how many times sweeter than sugar the compound actually is has never been measured: the number usually quoted traces to an uncited line and a solubility limit that makes the standard test impossible to run. The recipes describe the compound as relaxing the smooth muscle of the gut and releasing trapped gas, the old case for a cup of fennel after a heavy meal.
