Recipe Cook Time
In a saucepan, heat the 2 tbsp of oil and the butter over medium heat. When the butter has melted, add the flour and, using a wooden spoon or whisk, mix well.
Continue to stir or whisk for about 2 minutes, or until the flour is well blended.
Add 1/2 cup of the milk and increase the heat to medium-high. Bring the mixture to a boil and add the remaining cup of milk.
Cook, stirring constantly with the spoon or whisk, for about 5 minutes, or until the mixture begins to thicken.
Decrease the heat to medium and cook, stirring constantly to prevent lumps from forming, for about 10 minutes, or until thickened.
Add the chicken ham and stir. Cook for 1 minute longer and then pour the contents of the pan into the prepared dish.
Spread the mixture evenly. Let cool down for a bit and then cover and refrigerate for at least 2 hours, but preferably overnight to allow the mixture to set.
Spread the breadcrumbs on a dinner plate. With 2 spoons, shape the ham mixture into walnut-sized or golf ball sized croquettes.
Roll each croquette in the breadcrumbs, shaking off any excess crumbs, and then dip into the beaten egg.
Lift each croquette from the egg and roll it again in the breadcrumbs, coating it evenly.
Lay the croquettes in a single layer on a platter. Refrigerate for 30 minutes before frying.
Pour the oil to a depth of about 2 inches into a wide, deep, heavy pot and heat over high heat.
When the oil is almost smoking, slip 5 or 6 croquettes into the oil, pressing on them gently with a slotted spoon to submerge them, and fry, turning them gently, for about 2 minutes, or until they are golden on all sides.
Using the slotted spoon, lift out the croquettes, holding them briefly over the pot to allow the excess oil to drain, and transfer to an oven proof platter lined with paper towels to drain further.
Keep the croquettes warm in a low oven.
Fry the rest of the croquettes in the same way. Always making sure the oil is very hot before adding more croquettes.
When all the croquettes are fried, arrange on a platter and serve immediately.
