Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the vegetable oil in a large skillet or wok over medium-high heat until shimmering.
Add the black mustard seeds and cover the pan for about 30 seconds, until they start to pop.
Add the chopped garlic and crushed red chile pepper and stir for 30 to 60 seconds, until the garlic is fragrant and just golden.
Add the green beans, salt, sugar and ground black pepper, and toss to coat them in the spiced oil.
Stir-fry over medium-high heat for 8 to 10 minutes, until the beans are tender-crisp and lightly browned in spots.
If the beans start to stick or dry out, add a splash of water and cover the pan for a minute to steam them.
Taste, adjust the seasoning with a little more black pepper if you like, and serve hot.
