Ingredients

Alright, let’s make our shopping list! To make this recipe, you will need:

• Chinese Brocolli (gai lan): This recipe is versatile and can be used with many types of greens such as baby bok choy, choy sum, spinach and kale. In this recipe, my choice of greens is gai lan junior.
• Oil: Peanut oil or canola oil is a great choice.
• Garlic: Be careful when cooking the garlic. It can turn golden very quickly in hot oil and it also continues to cook in residual heat. Stirring constantly cooks the garlic evenly.
• Oyster sauce: I prefer using the LKK premium oyster flavoured sauce for best results.
• Water and sugar: These two ingredients balance all the flavours together.
• Sesame oil: Use this as a finishing oil after cooking to keep its delicious nutty aroma.
