I saw this recipe in a TV show. I found it interesting, especially since it was highly praised by the participants in that show. Until recently, I didn't use to cook wings, but after trying this recipe, they've become regular in our menu.
Wash well the chicken wings and drain the water.
In a bowl, combine the mustard with tomato paste, soy sauce, pepper.
If you notice that the sauce is very thick, add a little more soy sauce. Taste for salt and add more if you like it saltier.
And now the most beautiful part :)
Take each wing and, with your hands, coat well with this sauce, then arrange in an oven sheet.
Bake the wings in the preheated oven to 200 degrees C for about an hour , serve them with any favorite garnish.
Enjoy!
