A bit off topic, but most old Guernsey farmhouses had a "furze oven" - furze being the term used for gorse in Buernsey, and as Devonlady says, they used to burn gorse in the oven to heat is before baking bread etc. needless to say, they are mostly gentrified now as Guernsey farmhouses fetch huge prices and are owned by doctors,in private practice and lawyers! Bet they don't burn gorse in them!
