Common Mistakes to Avoid
When making the Black Pepper Beef Stir-Fry with Rainbow Peppers and Sesame Finish, there are some common mistakes to watch out for.
-
Skipping the Marinade: Not marinating the beef can lead to a less flavorful dish. Always allow the beef to soak in soy sauce and spices for at least 15 minutes.
-
Overcooking the Vegetables: Cooking peppers too long makes them soggy. Stir-fry them quickly over high heat to maintain their crunch.
-
Using Cold Meat: Adding cold meat directly from the fridge can lower the pan’s temperature, resulting in steaming instead of searing. Let the beef sit at room temperature for about 10–15 minutes before cooking.
-
Neglecting High Heat: A common error is cooking on low heat. For a proper stir-fry, ensure your wok is hot enough before adding ingredients to achieve that perfect sear.
-
Forgetting the Sesame Finish: Skipping the sesame oil or seeds can lose a key flavor component. Drizzle sesame oil right before serving and sprinkle sesame seeds for added flavor and texture.
