Essential Knife Skills for Home Cooks: Knives, Care, and Everyday Cuts for Proteins and Vegetables
Andy Cooks
Summary:
This video from Andy Cooks focuses on practical knife skills essential for home cooking, rather than complex culinary school techniques.
- Essential Knives: You only need four key knives: a chef's knife (24 cm), a small serrated paring knife, a serrated bread knife, and a boning knife (if you process meat/fish).
- Knife Care: Hand wash and dry knives. Sharpen with 1000 and 5000 grit wet stones (soaking the 1000 grit for an hour) at a 15-20° angle, then hone with a rod.
- Safety & Boards: Use a non-slip mat under your cutting board. Designate one board for raw proteins and another for cooked foods/vegetables.
- Protein Prep: Learn to break down a whole chicken (legs, thighs, wings, breasts), fillet fish (removing pin bones and skin), and cut beef against the grain for tenderness, also removing silver skin.
- Vegetable Prep: Master everyday cuts for onions (sliced, large dice, fine dice, rings), capsicum (diamonds, slices), broccoli (florets, stems), cucumber (discs, seed removal), carrots (grated, julienne, roasted, stir-fry, diced), garlic (minced, grated), spring onions (sliced white/green), and parsley (chopped).
- Carving: Prep a roast chicken by removing the wishbone and trussing for even cooking, then carve by removing legs and breasts. Carve roast beef against the grain, adjusting slice thickness based on the cut's tenderness.
Introduction to Essential Knife Skills [00:00]
Andy, a professional chef, shares practical knife skills that truly matter for home cooks, focusing on everyday tasks rather than intricate culinary school cuts.
Knife Care and Sharpening Fundamentals [01:34]
Proper knife care ensures safety and efficiency in the kitchen.
Proteins: Preparation and Cutting Techniques [07:54]
Knife Safety and Cutting Boards [07:54]
- Holding a Chef's Knife: Grip the handle with three fingers, placing your thumb and index finger on the front of the blade for maximum control.
- Holding a Boning Knife: Grip the handle firmly; do not hold the blade.
- Cutting Board Stability: Always place a non-slip mat, wet tea towel, or wet paper towel under your cutting board to prevent movement.
- Cross-Contamination: Use one cutting board exclusively for raw meat and fish, and another for cooked meat, vegetables, and other ingredients to prevent foodborne illness.
Breaking Down a Whole Chicken [08:57]
- Preparation: A whole raw chicken is placed on a cutting board, ready for butchery.
- Removing Legs: Slice the skin between the drumstick and breast. Bend the leg to pop the thigh bone out of its joint, then cut around the joint to remove the entire leg.
- Separating Thigh and Drumstick: Locate the joint between the drumstick and thigh with your finger and cut through it.
- Boning a Thigh: Run the tip of your boning knife along both sides of the thigh bone, then cut underneath to detach it.
- Removing Wings: Similar to legs, feel for the joint and cut through it. Detach wing tips for stock if desired.
- Removing Breasts: Identify the sternum bone running down the center. Make a deep cut along one side of the wishbone and sternum, following the rib cage to carefully detach the breast, including the tenderloin.
- Benefits: Saves money, allows for different cuts, and provides carcass for stock.
Filleting Fish [12:56]
- Preparation: A whole fish ready for filleting on a cutting board. You can optionally remove fins with kitchen scissors; be cautious of sharp, sometimes poisonous, dorsal fins.
- Initial Cuts: Run your blade from the top of the head down to the dorsal fin, then make an incision and carefully run the blade along the spine, staying close to the bone structure.
- Separating Fillet: Continue cutting along the rib cage, keeping the blade as close to the bones as possible.
- Belly Section: The belly can be tricky; work slowly, supporting the flesh as you cut.
- Carcass Use: Don't waste the carcass; scrape off any remaining meat and use the head and bones (after removing eyes and rinsing) for fish stock.
- Pin Boning: Feel for pin bones along the fillet with your finger. Use tweezers or small pliers to pull them out, supporting the surrounding flesh.
- Skinning (Optional) [16:40]
- Make a small cut at one end of the fillet to reach the skin.
- Angle your sharp knife slightly downwards, gripping the skin firmly, and move the skin back and forth against the stationary blade to separate it from the flesh.
- The skinned fillet is shown next to the removed skin.
Cutting Beef (Flank Steak) [17:41]
- Identifying Silver Skin: Silver skin is visible on a flank steak, indicating where to trim.
- Removing Silver Skin [17:49]
- Silver skin is a tough connective tissue on meat. Use the tip of your boning knife to get underneath it.
- Point the knife upwards and carefully run the blade to separate the silver skin from the muscle, minimizing meat waste.
- Cutting Against the Grain [18:38]
- Always cut beef (and lamb) against the grain.
- Identify the grain by looking for the long muscle fibers running in one direction.
- Cutting against the grain shortens these fibers, making the meat more tender.
- Demonstrate by showing how easily meat cut against the grain pulls apart compared to meat cut with the grain.
- Exceptions: Chicken and pork generally do not require specific grain-based cutting.
Vegetables: Everyday Cutting Techniques [20:01]
Learn essential, practical cuts for common vegetables for daily cooking.
Overview of Vegetables to be Cut
- An assortment of fresh vegetables including peppers, onions, garlic, carrots, broccoli, and herbs, displayed on a tray.
Onions [20:28]
- Sliced: Cut off the top and bottom, halve the onion, and slice with the grain using the "claw" technique (fingers curled, knuckles guiding the blade). Ideal for salads or caramelizing.
- Large Dice: Cut off top and bottom, halve. Make several horizontal cuts almost to the root, then turn and make vertical cuts.
- Fine Dice: Cut off the top, leave the root intact for stability, halve. Make thin horizontal slices almost to the root, optionally make vertical slices, then finely slice across using the claw technique.
- Rings/Slices: Cut off the top and bottom. Place the onion flat and slice carefully to desired thickness, using your palm to stabilize the round object.
Capsicum (Bell Pepper) [22:56]
- Preparation: Cut off the top and bottom, remove the core and white membrane.
- Stir-fry (Diamonds): Lay pieces flat, cut diagonally, then turn and cut diagonally again to create diamond shapes.
- Salad (Slices): Cut pieces into manageable strips, stack them, and slice.
Broccoli [23:46]
- Florets: Place the head down, cut off florets from the main stem. Break larger florets by inserting a knife into the stem and twisting.
- Stems: Peel any woody outer layers. Slice for stir-fries or blanching. Can also be grated and added to sauces like bolognese to add hidden vegetables.
Cucumber [24:54]
- Preparation: Cut off ends, halve lengthwise.
- Slices/Discs: Slice into discs. For salads, especially meal prep, scoop out the watery seeds with a spoon to prevent sogginess.
Carrots [25:16]
- Grated: For coleslaw or sofrito, grating is the easiest method.
- Julienne (Salad): Peel, cut one flat side to stabilize, then slice into thin planks, stack, and julienne.
- Roast: Leave skin on (if clean), cut into rustic, uneven shapes by slicing and rolling the carrot. These shapes create more surface area for caramelization.
- Stir-fry: Cut in half lengthwise, lay flat, and slice diagonally into 10mm thick pieces for quick cooking.
- Diced: Peel, quarter lengthwise, then dice into 1cm cubes.
Garlic [26:50]
- Mincing: Break open the bulb, remove cloves, cut off root ends. Smash cloves with the flat side of your knife to easily peel. Mince finely using the claw technique (rocking motion).
- Grated: For very fine garlic, use a microplane grater, ideally over a bench scraper to prevent it from touching the board.
Spring Onions (Scallions) [27:36]
- Preparation: An assortment of spring onions and parsley, ready for cutting.
- White Parts: Remove roots. Slice the white section (thicker for stir-fries, thinner for salads).
- Green Parts: Roll the green parts tightly, then slice finely at a sharp angle for garnish.
Parsley [28:16]
- Preparation: For home cooking, loosely pick leaves, a bit of stalk is acceptable.
- Chopping: Gather the picked leaves, scrunch them tightly, and roll them into a cigar shape. Slice once across to the desired fineness. Avoid multiple passes to prevent bruising and loss of color/vibrancy.
