Method
Use only one lemon if you prefer it less tangy.
- Boil the beans in salted water for 5-7 minutes until bright green and crisp, then shock in ice water and drain.
- Blend the garlic with oil into a spoonable paste.
- Heat a wide skillet or wok over high heat with oil to coat the base.
- Add the beans in a single layer and leave undisturbed for 1-2 minutes until blistered, toss, and repeat once.
- Add the garlic paste and toss for 1-2 minutes until fragrant, then move the beans to a serving bowl.
- In the same pan, toss the soy sauce, sugar, and sesame oil quickly until glossy and the sugar melts.
- Pour the glaze over the beans, add the lemon zest and juice, and salt generously to taste.
- Serve immediately, topped with sesame seeds or chilli flakes if you like.
