Using a food processor, chop the ham into tiny pieces.
In a pot, melt the butter, add the onions and cook them for about 3-5 minutes until translucent. While the onions are cooking, heat up the milk until it’s about to simmer.
Once the onions are translucent, add the half cup of flour and stir well. Once mixed, slowly add the milk to the mixture using a whisk to incorporate everything together. Continue to whisk until smooth and the mixture starts to boil. About 3-4 minutes
Add the chopped ham and stir until incorporated.
Place the mixture into the food processor. Add the parsley, salt, garlic powder, pepper, nutmeg and onion powder. Puree the mixture, to further incorporate the ham. About 3-4 minutes.
Place the ham filling into a bowl and place it in the fridge for about 2-3 hours. (The longer the mixture is in the fridge the better.)
Once chilled, scoop ham filling into your hands and roll into a log shape that measures about 2” long and 1” thick.
Place the plantain crumbs and flour on separate plates. Add the garlic salt to the plantain crumbs. Whisk the eggs in a bowl.
Once your logs are formed, dip them in the flour, then dip them in the egg and finally roll them in the plantain crumbs to give them a nice even coating. Repeat for all the logs.
In a deep fryer or on a pan, heat up oil to about 350°F. Place the croquetas in the oil for about 2-3 minutes, until golden brown. Transfer to plate line with paper towel.
Serve with lime! Enjoy!
