Common Mistakes to Avoid
Avoiding common mistakes can elevate your Japanese Zucchini dish to a new level. Here are some pitfalls to watch out for:

Overcooking the zucchini: Cooking zucchini too long can make it mushy. Aim for a tender but slightly crisp texture by monitoring the cooking time closely.
-
Using low-quality soy sauce: A poor-quality soy sauce can negatively impact the flavor of your Japanese Zucchini. Always choose a good-quality soy sauce for the best results.
-
Skipping the sesame seeds: The toasted sesame seeds add an essential crunch and nutty flavor. Don’t skip them; instead, sprinkle generously for added texture.
-
Not adjusting spice levels: If you’re sensitive to heat, start with less crushed red pepper flakes. You can always add more later, but it’s hard to reduce spice once it’s in.
-
Neglecting to chop evenly: Cutting zucchini into uneven pieces can lead to inconsistent cooking. Make sure all pieces are cut uniformly for even sautéing.
