Line Cooking Fundamentals

The line is where food gets cooked during service, whether that's in a fine dining restaurant, a hotel banquet kitchen or a hospital cafeteria. As a line cook, you work one station, such as grill, saute or fry, and your job is to put out the same dish, the same way, at speed. What separates a strong cook from a struggling one is preparation, technique, communication and staying organized under pressure.

What You Will Be Able to Do

• Build a station with complete mise en place before service.
• Choose and use the right cooking method for a food.
• Use knife cuts, stocks and sauces correctly.
• Hit doneness by temperature, and allow for carryover cooking.
• Read tickets, time a table and use kitchen language.

Mise en Place

Mise en place (MEEZ-on-PLAHSS) is French for "everything in its place". It means that all your ingredients, tools and containers are prepped and exactly where you expect them before the first ticket prints. Good mise is why a cook can stay fast and consistent. A cook who has to stop and chop an onion during a rush falls behind on every ticket.

Building Your Station

Keep cold items on ice or in a reach-in, and check them with a thermometer during service.

The Prep Routine

Line cooks often arrive 2 to 4 hours before service. Work through a checklist:

1. Check reservations or the event sheet to estimate volume.
2. See what's left from the last shift, and check dates.
3. Start anything slow first, such as braises and stocks.
4. Cut vegetables and prep garnishes.
5. Make and taste all sauces.
6. Set your station, with everything in the same place every day.
7. Ask the chef about specials, changes and anything 86'd.
8. Do a last taste and visual check of every component.

Knife Cuts

Uniform cuts cook evenly and look professional. Learn these sizes and practice them. The safety side of knife work is a separate skill, and it starts with a sharp blade and a claw grip.

A brunoise starts as a julienne. You cut across the matchsticks to get fine cubes.

Stocks and Sauces

Stock is made by simmering bones with vegetables and aromatics. The bones give it body and gelatin, and it's left unseasoned so that it can be reduced. Broth is made mainly from meat, and it's seasoned so that it can be eaten as it is.

The five classical mother sauces are the base for many others:

Small sauces such as bordelaise are made from a mother sauce. Bordelaise is built on a brown sauce with red wine.

To deglaze, add a liquid such as wine or stock to a hot pan and scrape up the browned bits, called fond. Those bits make a quick pan sauce.

Dry-Heat Cooking

Sauteing uses high heat, a little fat and frequent motion. Cut pieces evenly and keep them moving. Pan-frying uses moderate heat and more fat, and the food stays still to form a crust.

Don't crowd the pan. Too much food drops the temperature, so the food steams instead of browning. Browning, called the Maillard reaction, needs a hot, dry surface. That's also why you pat proteins dry.

Searing and pan-roasting: Heat the pan, add an oil with a high smoke point, and lay the protein in, away from you. Leave it until it releases on its own. Finish thick cuts in the oven.

If a pan starts to smoke heavily, pull it off the heat right away. The oil has passed its smoke point and may burn or catch. Check the food, and start again with fresh oil if needed.

Grilling: Preheat the grill thoroughly. Oil the food rather than the grates to reduce flare-ups. Use a hot zone for searing and a cooler zone for finishing. Don't press down on proteins, because that squeezes out juice.

Flat-top cooking: A flat-top must be fully preheated. Food that sticks and browns unevenly usually means the surface isn't hot enough yet or has hot and cold zones. Learn where your griddle runs hot, and scrape it clean between loads.

Roasting: Use higher heat for smaller items that need browning. Use lower heat for large roasts that need even cooking. A rack lets air circulate.

Deep frying: Most items cook at 325°F to 375°F. Keep the oil in that range by not overloading the basket. Drain on a rack, and season right away. Filter the oil daily, and change it when it darkens, smells off or foams.

Moist-Heat Cooking

Braising turns tough connective tissue into gelatin. A braise is done when it's fork-tender, not when the timer runs out.

Cooking to Temperature

Touch tests take years to learn. Use a thermometer.

Doneness is what the guest ordered. Food safety minimums are what your food code requires. They aren't the same thing.

These are common kitchen targets, and charts vary a little from one kitchen to another. Use your chef's standard. Whole-muscle steak cooked below 145°F is served only by request, and most codes require a consumer advisory on the menu. Serving undercooked food to highly susceptible people, such as hospital patients, usually isn't allowed.

Poultry and ground meat have fixed food safety minimums. Know them from your food code, and don't treat them as a matter of preference. The most common ones are 165°F for poultry and 155°F for 17 seconds for ground meat under the FDA Food Code.

Carryover cooking means the temperature inside meat keeps rising after it's off the heat, often by 5 to 10 degrees for a steak and more for a large roast. Pull proteins a little before your doneness target. Where a safety minimum applies, confirm the actual temperature with a thermometer rather than counting on carryover.

Resting lets juices settle back through the meat, so that they don't run out when you slice it. Rest steaks for about 5 to 10 minutes and roasts for 15 to 20. Build rest time into your ticket timing.

Tickets and Timing

How an Order Moves

1. The server enters the order, and a ticket prints or appears on a screen at each station.
2. The expeditor, or expo, calls it out: "Ordering, two salmon, one ribeye medium-rare."
3. Stations answer: "Heard."
4. The expo fires a course: "Fire table 12 entrees." That means start cooking those dishes now.
5. Stations call their times: "Two minutes on the salmon."
6. Plates land at the pass. Expo checks them and sends them to the table.

Working Backward

Every item for a table has to finish at the same moment. Know the cook time of each item on your station and count back from the finish.

Worked example. A table has salmon (8 minutes), a steak (10 minutes plus a 5-minute rest) and risotto (12 minutes). The longest is the steak at 15 minutes total. Start the steak at 0 minutes, the risotto at 3 minutes, and the salmon at 7 minutes. All three finish at minute 15.

Handling the Rush

• Work in order, starting with the oldest ticket, unless expo says otherwise.
• Batch similar items, such as dropping three orders of fries together.
• Keep talking. Silence on the line usually means that someone's falling behind.
• If you're in the weeds, say so early: "I need two minutes."
• Stay at your station and keep it clean. A messy station slows you down.

Kitchen Language

Short, loud calls prevent accidents and mistakes. Call them every time, even when it feels unnecessary.

Worked example. Three open tickets have 2, 1 and 3 burgers. The expo says, "Six burgers all day." That's the total you need to cook.

Cleaning as You Go

A dirty station is a slow one. Wipe boards between tasks, return tools to their place, and clear scraps as you make them. Change sanitizer buckets when they get dirty. Use separate cloths for raw food spills.

At the end of a shift, break down your station. Wrap, label and date all your prep. Clean and sanitize every surface, then sweep and mop your area. Restock for the next cook.

Common Mistakes

Check Your Understanding

1. The expo calls, "Four chicken all day." You have one ticket with two chicken sandwiches. How many should you be cooking?

Four. "All day" is the total across every open ticket, so there are other tickets you need to account for.

2. You lay six scallops in a small saute pan and they start releasing liquid. What went wrong, and what do you do?

The pan is crowded, or wasn't hot enough, so the scallops are steaming. Use a hotter or a larger pan, or cook them in two batches.

3. A guest orders a ribeye medium. Your chef's chart says 140°F to 145°F. At what point do you pull the steak?

A little early, usually about 5 degrees under the target, because carryover will finish it during the rest.

4. A coworker says "corner" as you're carrying a hot pan toward the same spot. What should you do?

Slow down or stop until they've passed. Call out "hot" so they know what you've got.

Key Takeaways

• Mise en place sets up everything else, so finish yours before service.
• Learn the cuts, the mother sauces and the basic dry-heat and moist-heat methods.
• Don't crowd pans. A hot, dry surface gives you browning.
• Use a thermometer, allow for carryover, and rest your meat.
• Doneness is a guest's choice, but safety minimums aren't.
• Communicate constantly, and time each table backward from the finish.
