My version of the ever-popular British Chinese takeaway dish of shredded sticky and crispy chilli beef with peppers will go from your fridge to your table in around 30 minutes and save you plenty of money!
Cut the beef into 2-3mm (⅛") thick strips across the grain of the steak.
Top and tail the onion, cut it in half and then into slices 5-6mm (¼") thick.
Remove the stems and seeds from the peppers and cut them into strips the same size as the onion.
Peel and grate the ginger.
Peel and mash the garlic into a paste.
Heat a 15cm or 6" saucepan over a medium heat and add all of the ingredients for the sauce, bring them to a boil, stirring constantly, then reduce the heat to low and simmer for 5 minutes.
Heat a dry wok over a high heat and toast the Szechuan peppercorns, and then crush them in a pestle and mortar.
Return the wok to the heat and add 3-4cm (1½") of neutral cooking oil and heat it to 180°C or 350°F.
Just before the oil is hot, place the beef in a bowl and add the salt, crushed Szechuan peppercorns and cornflour and mix well.
Fry the beef in batches for around 90 seconds, then remove and set aside on kitchen paper to absorb any excess oil.
Carefully drain almost all of the oil from the wok, leaving a scant coating and return it to a high heat.
Add the onions and pepper and stir-fry them for 90 seconds.
Pour in the chilli sauce and cook for 30 seconds.
Add the beef, stir to coat in the sauce and serve.
