Kafae boran (old-style Thai coffee)

กาแฟโบราณ: dark coffee and roasted grains dripped through a cloth sock, sweet with condensed milk

Before espresso bars reached Bangkok, coffee in Thailand meant kafae boran from Hainanese-Chinese shophouses and market carts: a dark robusta roast mixed with toasted grains, poured through a long cotton sock called a tung tom and stirred into thick sweetened condensed milk. Uncles still order it hot at 6 am with patongko dough sticks, and in the afternoon heat the same brew is poured over crushed ice and topped with evaporated milk as oliang or kafae yen. The taste is strong, roasty and slightly smoky, sweet and creamy, with a faint caramel-cereal edge from the grains; the iced version is silky and cold. The common mistake is brewing it like filter coffee with too little grounds: once milk and ice go in, it tastes thin. Use plenty, steep it in the sock and pour it through twice. The brew is ready when it is opaque, nearly black and leaves a brown film on a white spoon. It is high in caffeine, so not one for children or late evenings. Chef's tip: rinse the cloth sock in hot water only, never soap, and keep it in a jar of clean water in the fridge between uses so the coffee oils season it.

Method

0/4 done
  1. Step 1: Put the 1 ⅜ oz Thai old-style coffee powder (kafae boran) into a cotton coffee sock (or a fine cloth filter in a sieve) and hang it in a small heatproof jug or pot.

    1 min
  2. Step 2: Pour the 1 ½ cups boiling water over the grounds, let them steep in the sock for 2–3 minutes, then lift and drain. Pour the brew back through the sock once more; it should be opaque and almost black.

    4 min
  3. Step 3: Divide the 4 tbsp sweetened condensed milk between the cups or glass and pour in the hot coffee, stirring until the milk dissolves and the colour turns deep caramel.

    1 min
  4. Step 4: For hot kafae boran, float the 4 tbsp evaporated milk on top of the cups and serve at once. For the iced version, stir 2 tsp sugar into the hot coffee, pour over glasses packed with 10 ½ oz crushed ice and top with the evaporated milk.

Guava delight

A thick, fragrant blend of ripe guava, mango and banana, boosted with a spoonful of guava powder from the health shop. The book calls it a modern-day vitality drink, drawing on guava's long use in traditional Indian medicine. Serve it well chilled; sieve it if you don't like the little guava seeds.

Horchata de chufa

Horchata de chufa is the drink of Valencia's summer, sold ice-cold in the city's horchaterías with long, soft fartons pastries for dipping. It is made from chufas, or tiger nuts: small wrinkled tubers grown around the village of Alboraya just north of Valencia, which have their own protected designation of origin. Soaked, ground with water, strained and sweetened, they give a creamy, nutty, naturally dairy-free milk with a hint of cinnamon. Valencians drink it very cold, or half-frozen as 'granizada'. Chef's tip: soak the tiger nuts for a full 24 hours and change the water once; they must be plump and soft enough to blend into a fine pulp, or the horchata will be thin and taste of raw starch.
