London: Saffron Hill, EC1
Saffron Hill is the name of a street in the south eastern corner of the London Borough of Camden, between Farringdon Road and Hatton Garden. The name of the street derives from the fact that it was at one time part of an estate on which saffron grew. Source: Wikipedia
Saffron was grown in the gardens of John Kirby, Treasurer of the Realm, who acquired land here in 1272. Saffron was used in cooking to cover the taste of rancid meat. Source: What’s in a Street Name (Antony Badsey-Ellis)
