Khoai lang kén (sweet potato cocoons)

Sweet potato fritters

Khoai lang kén: mashed sweet potato logs rolled in shredded sweet potato and fried crisp

Hồ Chí Minh City street carts fry these little 'cocoons' in big woks, and on rainy evenings a paper bag of them, still too hot to hold, is a favourite with students and children. The inside is soft, sweet mashed sweet potato bound with a little rice flour; the outside is a shaggy, crunchy coat of fine sweet-potato threads that looks like a silkworm's cocoon. Eat them plain, or dip in sweetened condensed coconut milk. Chef's tip: squeeze the shredded sweet potato dry and keep the oil at 170 °C; wet shreds and cool oil give greasy, limp cocoons.

  • 1 ¾ oz glutinous rice flour

Method

0/6 done
  1. Step 1: Steam 1 ⅛ lb sweet potatoes for 15–20 minutes, until a knife slides through with no resistance. Mash smoothly while hot.

    18 min
  2. Step 2: Mix in 1 ¾ oz glutinous rice flour, 2 tbsp sugar and ¼ tsp salt and knead into a soft dough that no longer sticks to your hands; add a little more flour if it does.

    3 min
  3. Step 3: Rinse 10 ½ oz sweet potato in cold water, then squeeze out as much water as you can and pat it dry in a cloth. Toss with 2 tbsp tapioca starch.

    5 min
  4. Step 4: Roll tablespoons of dough into logs 6 cm long, then roll each firmly in the shreds, pressing so they cling all over.

    10 min
  5. Step 5: Heat 1 litre neutral oil in a wok or deep pan to 350°F (a shred dropped in fizzes at once). Fry 5–6 cocoons at a time, turning, for 4–5 minutes until golden brown and crisp, and lift out onto a rack.

    15 min
  6. Step 6: Let them cool for 3 minutes so the coating firms up, then serve warm.

Caramelised clay-pot tofu and mushroomsBraised tofu and mushrooms

Kho is the slow braise of the Mekong Delta: food simmered in a little clay pot (nồi đất) with dark caramel and seasoning until the sauce is sticky and the flavours go deep. This vegetarian cousin of cá kho tộ (braised fish) uses golden tofu and meaty mushrooms in place of fish, cooked in coconut water, as cooks do in the south, and finished with plenty of black pepper. Serve it bubbling in its pot with steamed rice and a sour soup or plain boiled vegetables. Chef's tip: take the caramel (nước màu) to a deep mahogany, darker than you think, just before it smokes; pale caramel only tastes sweet, while dark caramel gives the bittersweet, smoky flavour of a real kho.

Masala khakhraCrisp roasted wheat crackers

Khakhra are thin chapaties roasted slowly on a griddle until they turn crisp, like a cracker. This masala version adds gram flour, fresh fenugreek, turmeric and chilli to the wheat dough. They are a light Gujarati breakfast or tea-time snack, and lovely with pickle, chutney or a smear of butter. You can also make them in a roti maker.

Yaki onigiriGrilled rice balls

Yaki onigiri (焼きおにぎり) are rice balls grilled until they form a crisp, toasty crust, then brushed with soy sauce glaze. They are eaten all over Japan, at izakaya, at barbecues and from the freezer section, as a snack or with miso soup. The inside stays soft and steamy while the outside crackles. Best eaten hot, straight from the pan. Chef's tip: let the shaped rice balls dry for 10 minutes before they go in the pan. A drier surface forms a better crust and won't stick, and the glaze goes on only at the end so it doesn't burn.
