The café solo is pure espresso — small, black, intense, served in a tiny cup. The cortado is espresso cut with a cloud of milk — the most common order, the one locals get at the counter in the morning. The pulguita (literally "the little flea") is a micro-cortado: even less milk, even more coffee, in a liqueur glass. It's the coffee of old village men at 7am — strong, quick, no fuss. At the other end of the spectrum, café con leche is an espresso drowned in hot milk — that's what tourists order when they don't know what to get. The manchado ("stained") is the opposite: lots of milk, a stain of coffee. It's the snack of children and people who don't like coffee but still want to participate.
The leche-leche is the sweet drink of the Canaries: an espresso served in a glass, with a layer of sweetened condensed milk at the bottom and hot milk on top. No alcohol, no lemon, no cinnamon — just the sweetness of condensed milk that caramelizes the coffee. It's the compromise between coffee and dessert. Canarians drink it at any time — breakfast, after lunch, snack time, late evening. If the barraquito is Canarian coffee's Sunday suit, the leche-leche is its everyday outfit.
The "pérez" is a café largo (lengthened) with a dash of cold milk — a specialty of Santa Cruz and La Laguna, practically unknown in the touristy south. The "carajillo" is an espresso dosed with brandy, anise or rum — the pick-me-up at 5pm for old fishermen and farm workers. The "café de olla" (pot coffee), which is made with gofio, honey and cinnamon, is a remnant of mountain peasant cooking — you can still find it at village festivals and romerías. And in La Gomera, the "café gomero" is a spectacle: it's poured from a height of 50 cm from one container to another to make it foam, with honey liqueur — it splashes, it foams, and it's a ritual.
Rule #1: specify the container. "En vaso" (in a glass) gives you more milk. "En taza" (in a cup) gives you a more concentrated volume. Rule #2: state the temperature of the milk. "Natural" = room temperature. "Del tiempo" = cold. Hot milk is the default. Rule #3: never ask for plant-based milk in a village bar — they don't have it and will look at you strangely. The cafés in La Laguna and Santa Cruz have it. Rule #4: the price. At the counter (barra): €1-1.50. On the terrace (terraza): €1.50-2.50. A complete barraquito: €2.50-4. Tenerife is one of the last places in Europe where a good coffee won't break the bank.
