Kopi tubrukBoiled coffee with sugar
From the warung kopi of Yogyakarta and Solo to the night-shift stalls of Surabaya, kopi tubruk is the everyday coffee of Java: powder-fine robusta and sugar spooned into a glass, hit with boiling water, stirred once and left alone while the grounds sink. It comes out black, thick and strong, with a toasty, slightly chocolatey bitterness and often plenty of sugar, drunk early with fried snacks and again late at night over long talk. The grounds sit as a muddy layer at the bottom and stay there. The common mistake is drinking or stirring too soon: the cup is gritty and harsh. Wait four or five minutes, until the crust on top sinks and the surface turns clear and dark, then sip gently and stop before the sludge. It is ready when the foam has collapsed and a thin oily sheen shows on top. This is a strong, high-caffeine coffee; one glass is plenty, and it is not for children. Some sellers add a slice of ginger or a pinch of cardamom. Chef's tip: grind the beans as fine as for espresso or finer; coarse grounds float and never settle.
