Biscoito de polvilho

Crunchy cassava starch rings

Biscoito de polvilho: hollow, crunchy Minas rings piped from sour cassava starch, egg and oil

Light enough to float off the plate, these rings are sold by the bagful at bus stations, beaches and football grounds all over Brazil, but they belong to Minas Gerais, where sour cassava starch (polvilho azedo) has been made for centuries. Scalding the starch with hot milk, water and oil and then beating in eggs gives a sticky paste that puffs in a hot oven into crisp, airy, slightly tangy shells. Mineiros eat them with coffee in the afternoon or nibble them all day. Bake them in a hot oven and do not open the door: the rings collapse into flat, hard discs if the heat drops in the first 20 minutes. Chef's tip: the paste should pipe like thick mayonnaise; add a spoon of water if it is too stiff, because a soft dough is what makes the biscuits hollow.

Method

0/7 done
  1. Step 1: Heat the oven to 400°F (350°F fan) and line two baking trays with baking paper. Put 1 ⅛ lb sour cassava starch (polvilho azedo) and 2 tsp salt in a large bowl.

  2. Step 2: Bring ¾ cup whole milk, ¾ cup water and ¾ cup neutral oil to the boil in a pan over a medium heat.

    4 min
  3. Step 3: Pour the boiling liquid over the starch and mix with a wooden spoon until it forms a lumpy, crumbly mass. Leave for 5 minutes, until just warm.

    5 min
  4. Step 4: Add 2 eggs one at a time, beating hard with the spoon or a mixer after each, until the dough is smooth, sticky and thick enough to pipe. Add 1–2 tablespoons of water if it is stiff.

  5. Step 5: Spoon into a piping bag with a 1 cm plain or star nozzle and pipe rings about 7 cm across, well spaced, onto the trays.

  6. Step 6: Bake for 25–30 minutes without opening the oven door, until puffed, dry and very lightly golden. They should sound hollow when tapped.

    28 min
  7. Step 7: Turn off the oven and leave the biscuits inside with the door ajar for 10 minutes to crisp. Cool on a rack and store in an airtight tin for up to a week.

PingadoHot milk with coffee

Order 'um pingado' at the balcão of any São Paulo padaria at 7 in the morning and the attendant pours hot milk into a ridged glass tumbler (the copo americano) and 'drips' in a splash of strong coffee, hence the name. It is milkier and gentler than a média (half coffee, half milk), creamy and lightly sweet, usually drunk standing up with a pão na chapa, a toasted buttered roll. At home you need strong filter coffee and milk heated until steaming. Scalding the milk is the frequent mistake, as boiled milk tastes flat and forms a skin. Chef's tip: froth the hot milk for a few seconds with a whisk or by pouring it back and forth between two jugs before adding the coffee, as padaria machines do.

Basque burnt cheesecake

This crustless cheesecake was created in the early 1990s at La Viña, a pintxos bar in the old town of San Sebastián (Donostia) in the Basque Country, and is now famous around the world. It's baked very hot so the top caramelises almost black and the sides rise and crack, while the middle stays soft and creamy, almost runny. There's no base and no water bath, and the rough, rustic look is the point: it's lined with crumpled baking paper. La Viña uses a spoonful of wheat flour; cornflour does the same job and keeps it gluten free. Chef's tip: take it out of the oven while the centre still wobbles like a soft set custard; it firms up as it cools, and if it looks set in the oven, the middle will be dry instead of creamy.
