Will using home-made tomato sauce instead of egg, work for Fried chicken?

Is homemade tomato sauce a good substitute for egg when making fried chicken? I’m planning to create a popcorn chicken-style dish and am weighing the options below. I’d love to get everyone’s opinions!

1) Marinate the chicken with salt, garlic, and black pepper for an hour. Then coat it in a tomato sauce (made with sunflower oil, tamarind, and garlic) before dredging it in a mix of flour and cornstarch. Let it rest for 10 minutes before frying.

2) Simply marinate the chicken in the sauce and then coat it in flour and cornstarch. I might also consider adding an egg to this option.

Thanks in advance for your input! 😄

Edit: It worked! While it wasn’t exactly like KFC or Karaage, it turned out surprisingly crispy without using egg. I can’t post a picture here, but you can check it out on Reddit: https://www.reddit.com/u/One_Independent_4675/s/dHecaHZLQR.

In terms of flavor, it was a total explosion wherever the tomato sauce was applied—much more delicious than KFC. I couldn’t debone the chicken myself, so I opted for larger pieces.

Recipe:

Marinate: Chicken, dried oregano, dried basil, chili flakes, red wine vinegar, plenty of soy sauce, salt, turmeric, and red chili powder.

Timing: I kept the marinated chicken in the fridge for 2 hours, then added the sauce for an additional hour after removing the initial marinade.

Tomato Sauce: Mustard oil, onion, garlic, tomato puree, tamarind, optional curry leaves, hing, a bit of the initial marinade, and red wine vinegar.

Preparation: Cook the onions until browned, then add garlic followed by the other ingredients.

For the second marinade: I sautéed onion paste and garlic for 10 minutes, as I felt the sauce needed more flavor.

Finally, I coated the chicken with a blend of equal parts cornstarch and all-purpose flour, along with 2 teaspoons of garlic powder. I let it sit for 20 minutes before frying.
