Boil the spaghetti in enough salted water and drain into a sieve. In the meantime, heat the oil in the wok, cut the spring onions, the garlic cloves and the basil leaves into small pieces and fry them in the wok for approx. 2 minutes.
Add the prepared shrimp together with the butter and fry for another 4 minutes. Pour in the vegetable stock and lemon juice. Now season everything vigorously with salt and sambal oelek and simmer over a low heat for 5 minutes.
Fold in the drained spaghetti and mix everything together. If necessary, season again.
