Thickening Trick – If the sauce is too thin, mix 1 teaspoon of cornstarch with 2 teaspoons of water, then stir it into the sauce while simmering.
Use Fresh Pineapple – For a natural sweetness and juicy texture, swap canned pineapple for fresh chunks.
Make It Spicy – Add red pepper flakes, sriracha, or diced chili for a bit of heat.
Gluten-Free Option – Use a gluten-free flour blend for the batter and tamari instead of soy sauce.
Meal Prep Friendly – Prepare the sauce in advance and store it in the fridge for up to a week for quick assembly.
