Beef Stir-Fried with Wild Betel Leaf

Method

1. 1 Wash the betel leaves, then cut them into 1 cm wide strips and let them drain completely.
2. 2 Marinate thinly sliced beef with cornstarch, chopped lemongrass, and fish sauce for 20 minutes.
3. 3 Sauté the beef in a very hot pan over the highest heat for 90 seconds, then remove it from the pan.
4. 4 Sauté the garlic, then stir-fry the onions for 90 seconds.
5. 5 Add the beef back in, turn off the heat, and then mix in the betel leaves using the remaining heat of the pan.
6. 6 Betel leaves only need residual heat to soften; stir-frying them over high heat will cause them to turn black and lose their aroma.
