Crispy chilli beef always takes me back to the excitement of opening up a takeaway box at the dinner table but now I can make it even better at home with bold flavors and the perfect homemade crunch This recipe delivers just the right balance of sweet spicy and tangy with beef that stays wonderfully crispy
I still remember the first time I nailed the crispy coating My husband asked if we had started a new Friday night tradition and we truly never looked back
Ingredients
- Sirloin steaks: sliced very thinly for that perfect quick cook tip use partially frozen steak for easier slicing
- Egg: helps the cornflour stick to the beef and creates that irresistible crispy coating use the freshest eggs you can find
- Cornflour: also called cornstarch this is the secret to super crispy beef check for any lumps before using
- Salt and black pepper: season the beef at its base plus a touch of white pepper for a warm background note grind fresh for best flavor
- Sunflower oil: neutral flavor and high smoke point ideal for stir frying make sure it is clear and golden
- Onion: sliced into thin strips for sweetness and texture select firm onions with papery skins
- Red chilli: adds heat and color to the dish choose fresh chillies that are firm to the touch
- Minced ginger: bright spicy lift use a plump piece with smooth skin
