The secrets behind perfect battering

Coating homemade cod croquettes is an art form that requires technique and patience. The key lies in the traditional three-step breading process : flour, beaten egg, and fine breadcrumbs. Each layer acts as a protective barrier that seals in the flavors and creates that coveted crispy texture.

For an exceptional coating, the béchamel sauce must be completely cold before breading. This temperature allows the batter to maintain its shape during the process. Homemade breadcrumbs, lightly toasted, provide a superior texture to store-bought ones.

"The trick is to let the breaded croquettes rest in the refrigerator for at least 30 minutes before frying. This allows the breading to adhere perfectly to the béchamel sauce."

Exact proportions for a silky béchamel sauce

Béchamel sauce is the heart of exceptional homemade cod croquettes. The classic proportions call for 100 grams of butter, 100 grams of flour, and one liter of whole milk. However, the real secret lies in the gradual addition of the milk.

First, a golden roux is prepared with the butter and flour. It should be cooked for exactly three minutes to eliminate the floury taste. Then, the milk is added warm, never cold, to avoid unwanted lumps.

The perfect cooking point

The ideal texture is achieved when the béchamel sauce completely coats a wooden spoon without dripping. This critical point determines whether the croquettes will maintain their shape or spread out during frying. A béchamel sauce that is too thin will result in croquettes that fall apart, while one that is too thick will make them difficult to shape.

Ingredient Amount Function
Butter 100g Fatty base of the roux
Flour 100g Main thickener
Whole milk 1 liter Base liquid
Salt cod 400g Star of the filling

Cod: selection and masterful preparation

The quality of the cod determines the final success of the recipe. Icelandic cod, with its firm texture and delicate flavor, becomes the star ingredient. It must be desalted for 48 hours, changing the water every 8 hours to completely remove the salt.

Once desalted, the cod is shredded into thick strands, respecting the fish's natural fibers. This manual process preserves the texture and prevents it from becoming a uniform paste.

Fish cooking techniques

The cod is cooked briefly in the same béchamel sauce, absorbing the dairy flavors while imparting its marine essence. Three minutes of cooking is enough for the fish to blend in without losing its individual character. The temperature should not exceed 80 degrees Celsius to maintain a silky texture.

Professional tricks for guaranteed success

Professional chefs know secrets that make all the difference. The first is to cool the béchamel sauce on a tray, covered with cling film in direct contact with the surface to prevent a skin from forming.

  • Use mild olive oil at exactly 180°C
  • Shape the croquettes with slightly damp hands
  • Fry a few units at a time to maintain the temperature
  • Drain immediately on absorbent paper

When is the exact moment to remove the croquettes from the oil? When their surface is evenly golden brown and they sound slightly hollow when gently tapped with a slotted spoon. This critical point guarantees a crispy exterior and a creamy interior.

The final resting time, just two minutes on absorbent paper, allows the flavors to settle and the temperature to equalize. Serving immediately ensures the perfect gastronomic experience every foodie seeks.
