One of the more challenging classical seafood dishes  I know of requires fabricating a whole fish in to perfectly even darnes, trussing the darnes and then gently poaching in a Court Bouillon.
While the darnes are still quite hot, the pin bones need to be pulled (they are on a diagonal), the butcher twine needs to be cut away, the skin needs to be peeled and the seafood must be plated without breaking... and served piping hot with Sauce Hollandaise & boiled, tourneed potatoes.  I repeatedly practiced this dish for the CMC exam with a whole salmon... quite the challenge!

Darne of Salmon   

Fabricating seafood is a tremendous amount of work, requiring experience, proper technique, patience & the correct tools. One of my responsibilites at my first professional cooking jobs was 'fish butcher'. I loved it and remember the fins, bones, gills etc... constantly pricking my fingers when I fabricated a large variety of seafood. Cuts from fish are no fun, they get infected and take a very long time to heal!

These days I wear thick gloves for protection & use strong shears, tweezers, boning knives and a small cleaver to make the job more manageable.

I believe most consumers refer to the thick, cross cut (skin on and with bones) of whole fish as a steak. Chefs call this cut a darne! I rarely see darnes of seafood at national grocery stores but often see this cut at Asian markets.

 There is a small portion of the back bone in the cut which holds he fish together nicely but trussing with butcher's twine is the best way to hold the darne together.


I like to poach the darnes although it's perfectly delicious sautéed or grilled.


These pictures are taken at an outdoor food market in Malaysia. There are many different types of seafood of all shapes and sizes-freshly caught daily.

 

Poached Darne of Salmon

Prep Time: 10 min

Cooking Time: 20 min

Yield: 4 portions


Ingredients                                          

4 ea.            Seafood 'steaks'/darnes (salmon, striped bass, cod)

4 Cups       Water

1 Cup           Vinegar (red wine/cider)     

1 Cup           Mirepoix, sliced thin                

1  Tbsp        Kosher Salt                                       

12 ea            Black peppercorns

1 ea              Lemon, sliced thinly

3 ea.            Green onions, sliced thinly 

3 Tbsp       Bay leaves



How to Prepare Poached Darne of Salmon

Step 1

Have your seafood butcher fabricate the seafood carefully to eliminate all scales, grills, fins and blood.

Also request the portions are all the same in size, weight and appearance. Since fish have much different thickness at the tail end than in the middle, the portions may be dramatically different. (and will cook differently).



Step 2 Preparing Court Bouillon

Place the water, mirepoix, lemon slices, vinegar, bay leaves, herbs, seasonings into the pan you will poach the fish in and bring to a boil; simmer for 5 minutes. You can strain if you like.







Place the darnes into the hot court bouillon, making certain the darnes are fully submerged. Allow the fish to poach gently for about 10 minutes at 165 ° F, until the darnes reach an internal temperature of 145° F. Do not boil!







Step 3 

Place the cooked darnes on to a plate, cut the strings off-discard. Carefully trim the skin, blood line and bones from the darnes. You may choose to return the salmon in to the hot court bouillon for a minute or so to reheat after trimming-be careful and use a perforated spatula to avoid breaking the fish.

I remember learning to make an emulsion sauce for called Rouille at Le Cirque. It's one of my favorites! Rouille is a delicious, classic French garlic mayonnaise served with bouillabaisse, a famous, French fish soup. I was taught to use EVOO, saffron, garlic etc... and cooked potato in the recipe. Other famous emulsion sauces include aioli, vinaigrettes, dressings, etc...

Biscotti translates to 'twice baked' and apparently was a popular snack for Roman soldiers since the biscotti lasted for days without getting stale. I read Christopher Columbus had biscotti stored away on his voyage to America... In Tuscany, biscotti and vin santo is considered by many to be a perfect pairing. I enjoyed this combination at a cafe in Florence years ago... I love dipping crunchy biscotti into a cup of strong black coffee.

The Classical French cooking segment during the CMC exam was extremely difficult for me! Although the format changes slightly from exam to exam, I was required to prepare C onsommé Florial; a baked, Dover Sole course and Roasted Lamb chops with pistachio forcemeat for 10 people-with appropriate sides and sauces. It was probably the hardest day of the 10 day exam for me. I sourced frozen peas (fresh peas were not in season) for the consommé and completely forgot to use them as garnish for my soup! I barely passed that day and managed to totally annoy one of the nicest CMC evaluators... never a smart thing to do! But I still love preparing and eating delicious consommé-great satisfaction when it comes out crystal clear.

I think my favorite cobbler was a recipe I developed with Chef Joshua Mackintosh for an ACF student chef competition. We used raspberries, blueberries, strawberries & dark chocolate chips for the filling. It was delicious. Josh came in second place... hmmm \I'm not sure I agreed with that evaluation! hahaha
