Libyan tea is judged a failure if it arrives without a thick foam on top — vendors build that foam by pouring the tea cup-to-cup, held an arm's length apart, three times over.
Strong black tea is boiled down in a small stovetop kettle, sweetened heavily, then poured back and forth between glass and kettle from a height until a thick tan foam sits on top. Street kiosks and home stalls in Tripoli serve it in small glass cups, usually in three rounds, with the final round often accompanied by boiled peanuts or almonds.
