📖 Instructions

1. Prep the Beef: Slice the beef sirloin thinly against the grain into approximately 2-inch long strips. This ensures maximum tenderness. Place the beef strips in a bowl.
2. Marinate the Beef: In the bowl with the beef, add 1 tablespoon of soy sauce, 1 teaspoon of cornstarch, and 1/2 teaspoon of sesame oil. Mix well to coat the beef evenly. Allow the beef to marinate for at least 15 minutes. This helps tenderize the beef and infuses it with flavor. If you have more time, you can marinate it for up to an hour in the refrigerator.
3. Prepare the Zucchini: Wash the zucchini thoroughly. Trim off both ends, and then slice it into half-moons about 1/4-inch thick. Set aside.
4. Mince the Aromatics: Mince 2 cloves of garlic and grate about 1 teaspoon of fresh ginger. Having these aromatics ready to go will make the stir-frying process smooth and efficient.
5. Mix the Curry Sauce: In a small bowl, whisk together 2 tablespoons of soy sauce, 1 tablespoon of curry powder, 1 tablespoon of honey (or maple syrup for a vegan option), and 1 teaspoon of rice vinegar. Ensure there are no clumps of curry powder and that the honey is fully dissolved. Taste and adjust seasonings as needed. You might want to add a pinch of salt or a dash of chili flakes for extra heat.
6. Heat the Wok: Place a wok or large skillet over high heat. Add 1 tablespoon of vegetable oil. Wait until the oil is shimmering and almost smoking – this is crucial for getting that wok hei (smoky wok flavor).
7. Stir-Fry the Beef: Add the marinated beef to the hot wok in a single layer. Stir-fry quickly for about 2-3 minutes, or until the beef is browned on all sides but still slightly pink inside. Remove the beef from the wok and set aside. Avoid overcrowding the wok, as this will steam the beef instead of searing it.
8. Sauté the Aromatics: Add another 1 teaspoon of vegetable oil to the wok if needed. Add the minced garlic and grated ginger. Sauté for about 30 seconds, or until fragrant. Be careful not to burn the garlic, as it can turn bitter.
9. Add the Zucchini: Add the sliced zucchini to the wok. Stir-fry for about 3-4 minutes, or until the zucchini is tender-crisp. It should still have a bit of bite to it.
10. Combine and Finish: Return the cooked beef to the wok with the zucchini. Pour the curry sauce over the beef and zucchini. Stir-fry for another 1-2 minutes, or until the sauce has thickened slightly and everything is well combined.
11. Garnish and Serve: Remove the wok from the heat. Garnish with sesame seeds and chopped green onions. Serve immediately over rice or noodles. Feel free to add a dollop of plain yogurt or a squeeze of lime juice for extra flavor.
