2½ tbsp tom yum paste (we like Blue Elephant Tom Yam Chili Paste)
200g frozen raw prawns
200g mixed frozen beans and peas
200g dried rice ribbon noodles
225g tin water chestnuts, drained and rinsed
225g tin bamboo shoots, drained and rinsed
1 tbsp light brown soft sugar
Fish sauce or soy sauce to taste
2 limes for squeezing
4 spring onions, sliced thinly lengthways, to serve
Bring the stock to the boil in a large pan and stir through the tom yum paste. Add the prawns, simmer for 2 minutes, then add the beans and peas. Simmer for 5 minutes.
Meanwhile, cook the noodles according to the packet instructions. Drain, then rinse with cold water. Divide among warmed bowls.
Add the water chestnuts and bamboo shoots to the soup and simmer for 2 minutes to warm through. Season to taste with the sugar, a good splash of fish sauce or soy sauce and lots of freshly squeezed lime. Ladle the hot soup over the noodles and sprinkle over the spring onions to serve.
