How to make Salt Cod Croquettes.
4 tbsp Spanish extra virgin olive oil
4 tbsp butter
1 quart milk
2 cups flour
¼ cup cornstarch
250grams Salt cod, diced (cod should be desalted)
1 onion, diced
1 tsp salt
zest of 1 lime
1 tsp oregano
3 cups bread crumbs
2 cups flour
In a small bowl, mix the cornstarch in ¾ cup of the milk and set aside.
Prepare a baking sheet tray with at least a one inch edge. A cookie sheet works great.
In a saucepan, warm the milk with oregano and zest of lime and set aside or keep on low heat until needed.
Heat a medium sized pot over med-low heat, add the butter and olive oil and sauté the onions until soft and translucent. Add cod and lightly sauté 1-2 minutes.
Add the flour to the pot and mix to form a roux. Pour the milk slowly and mix with a whisk. Add the cornstarch mixture. Mix well and cook over low heat for 5 minutes. Then pour onto the baking sheet tray and spread it out evenly. Let cool for one hour, uncovered.
Fill a pastry bag with the cooled mixture and cut off the tip of the bag to make a 1 inch hole. Prepare your second sheet tray with about ½ inch layer of flour. Pipe a long tube of mixture onto the tray and continue until you have piped all of the mixture onto the tray and you have about 5-6 tubes.
Cut into 2-3 inch logs and dredge well in flour on all sides. In a shallow dish, beat the eggs with a little water and spread breadcrumbs on a cookie sheet or shallow dish. Dredge each croquette in the egg mixture, then the breadcrumbs and place on a clean tray.
Fill a heavy pot with enough frying oil to be 2-3 inches deep. Heat to 350 F and fry until golden brown on each side. Serve warm with alioli sauce.
