You will need (for two):
150g beef cut into strips
A few tbsp flour, seasoned with salt, pepper and cayenne
Groundnut oil
A few large purple kale leaves, cut into thin strips
1 large chilli, sliced
2 garlic cloves, sliced
4 spring onions, sliced
3 tbsp dark soy sauce mixed with 2 tbsp sugar and 2 tbsp rice wine vinegar
Noodles to serve
Get a wok on a high heat and add about 1cm of groundnut oil. While the oil heats up mix the beef with the seasoned flour until it’s all coated. When the oil is smoking add the beef and fry for about a minute or until cooked and crispy. Remove the beef from the wok and place to one side. Pour away any excess oil but leave a little to cook the vegetables.
Add the kale to the wok and fry for about 30 seconds before adding the chilli, garlic and spring onions. After a minute or so add the soy sauce mix and then put the beef back in. Serve on top of some noodles.
A tip: this stir fry tastes great because everything is cooked in smoking oil but this can lead to slight choking as the kitchen fills with smoke. I would put the extractor fan on full blast and tape down any toupées.
