Sopa de letras (Mexican alphabet soup)

12m+ · Toasted alphabet pasta in a light tomato and vegetable broth

Sopa de letras is the soup almost every Mexican child grows up on, served as the 'sopa aguada' course at the midday meal: tiny letter-shaped pasta, toasted golden in oil, then simmered in a broth of blended tomato, onion and garlic with soft diced carrot. For toddlers it is made with a no-salt vegetable stock, so the sweetness of the tomato comes through. It contains gluten (wheat); it has no milk, egg, nuts, soya, sesame or fish. Chef's tip: toast the pasta until it smells nutty and turns light gold; that is where the flavour comes from.

Baby & toddler safety

  • Age: from 12 months+.
  • Allergens: contains gluten (wheat, barley, rye or oats). Offer one new allergen at a time, in the morning, so you can watch for a reaction.
  • Texture and choking: purée or mash smoothly for 6–9 months, then soft, finger-sized pieces that squash between your fingers. Cut round foods such as grapes and cherry tomatoes into quarters lengthways, never give whole nuts, and always stay with your child while they eat.
  • Under 1: no honey, no added salt or stock cubes, and no added sugar.

Every child is different. If you are unsure, especially about allergies, check with your health visitor or paediatrician.

Method

0/6 done
  1. Step 1: Blend 2 ripe tomatoes, ¼ onion and 1 garlic clove with a splash of water until completely smooth.

    2 min
  2. Step 2: Heat 1 tbsp vegetable oil in a saucepan over a medium heat. Add 2 ⅞ oz alphabet pasta and stir constantly for 3–4 minutes, until most of the letters are light golden and smell toasty. Don't walk away: the common mistake is letting them go dark brown, which tastes bitter.

    4 min
  3. Step 3: Pour in the tomato mixture carefully, as it will splutter, and stir for 2 minutes until it darkens slightly and thickens.

    2 min
  4. Step 4: Add 3 ¼ cups no-salt vegetable stock, 1 carrot and 1 ⅜ oz frozen peas, if using. Bring to the boil, then simmer for 10–12 minutes, until the pasta is very soft and the carrot squashes easily with a spoon.

    12 min
  5. Step 5: The soup thickens as it stands; add a splash of water if needed. Ladle into a bowl and cool until warm before serving. Adults can season their own bowls with salt and lime.

  6. Step 6: Cool leftovers quickly and keep covered in the fridge for up to 2 days, or freeze for up to a month (the pasta softens further). Reheat until piping hot, then cool before serving.

Tiyula itumBlack beef soup

Tiyula itum, 'black soup', is the pride of the Tausug people of Sulu in the far south of the Philippines, cooked for weddings, Eid celebrations and when guests come home. Beef (it is a halal, pork-free dish) is simmered with ginger, lemongrass and turmeric, then darkened with pamapa itum, a paste of grated coconut toasted until almost black and pounded with spices. The broth looks dramatic but tastes smoky, earthy and gently peppery, with heat from chillies. Serve it with plain rice. Chef's tip: toast the coconut slowly, stirring all the time, until it is very dark brown but not ashy; burnt-to-ash coconut tastes bitter and ruins the soup.

Black bean tacos with lime slaw

Proof that a meat-free taco night can be the best one. The beans are mashed with chipotle and cumin so they hold together in the tortilla, and a quick lime slaw adds crunch.

Ful nabitSprouted fava bean soup

Sprouted beans are ladled out with their cooking liquor in Cairo homes when the weather turns cold or someone is feeling run down, and Egyptians swear by the broth as a pick-me-up. The beans are soaked and left to sprout for a few days, then simmered with onion, garlic and cumin into a light, earthy soup that is sharpened at the table with plenty of lemon. You can eat the beans with a spoon or pop them from their skins. Allow 3 to 4 days for sprouting, although the hands-on work is only about 20 minutes. People with G6PD deficiency (favism) must not eat fava beans. Chef's tip: stop the sprouting when the shoots are about 1 cm long; longer sprouts taste grassy and bitter.
