Take one onion and start peeling them, then cut off the side without the root, closer to the half of the onion. After they are peeled, place them under water to clean them. Dry them using a paper towel, and start cutting the onion in 16 or 32 equal pieces (cut diagonally). Now to achieve the flower look, you will have to gently separate the onion pieces. You should place it in the refrigerator for 1-2 hours, this will help you in the process. Take out a bowl and combine the salt with the flour, the peppers and the herbs. Pour the flower on the onion and make sure to cover between the buds too. Combine the milk with the eggs and put the onion in the mixture and cover it again with the flour. Pour oil into the frying pan and place the onion inside. Make sure to add enough oil to cover the whole onion. Place the onion upside down in the pan and fry for 2-3 minutes, until it becomes golden brown. Now turn it on the other side and fry again for 2-3 minutes. Place it on a paper towel and remove the center of the onion, using a sharp knife. The dipping sauce will be placed here. You can add any kind of dip you like, just place it inside the onion and enjoy this cool appetizer.
