Lesson 2: Knife Skills and Food Preparation

Objectives

By the end of this lesson, you’ll be able to: - Hold and use a knife safely and effectively - Master basic cutting techniques (chopping, dicing, slicing, mincing) - Prepare common vegetables and fruits efficiently - Understand different knife types and their uses - Maintain and care for your knives properly

Why Knife Skills Matter

Let’s be honest—watching professional chefs effortlessly dice an onion in seconds can be intimidating. But here’s a secret: good knife skills aren’t about speed (at least not initially). They’re about consistency, safety, and efficiency.

Developing proper knife skills will: - Save you time in the kitchen (prep work often takes longer than actual cooking) - Improve your dishes (evenly cut ingredients cook more uniformly) - Reduce waste (better control means less food in the bin) - Keep all your fingers attached (rather important, I’d say)

So let’s cut to the chase (sorry, not sorry) and transform your relationship with the most important tool in your kitchen.

Choosing Your Weapons: Knife Basics

The Only Three Knives You Really Need

Forget those massive knife blocks with 17 different blades. For 95% of cooking tasks, you only need three knives:

Chef’s knife (20-25cm/8-10 inch): Your all-purpose workhorse for chopping, slicing, and dicing
Paring knife (8-10cm/3-4 inch): For detailed work like peeling, trimming, and small cutting tasks
Serrated knife (20-25cm/8-10 inch): For bread and slicing soft foods with tough exteriors (like tomatoes)

If you can only afford one quality knife, make it a chef’s knife. It’s the Swiss Army knife of the kitchen.

Knife Construction Basics

A good knife has: - Full tang: The metal extends through the entire handle for balance and durability - Forged (not stamped) blade: Generally stronger and holds an edge better - Comfortable grip: Should feel like an extension of your hand

Materials matter too: - High-carbon stainless steel: Good edge retention, rust resistance - Damascus steel: Beautiful but expensive - Ceramic: Ultra-sharp but brittle

For beginners, a mid-range stainless steel chef’s knife (£30-60) offers the best balance of quality and value.

The Proper Grip: Power and Control

How you hold your knife is the foundation of good technique. There are two main grips to master:

The Pinch Grip (For Most Cutting Tasks)

Pinch the blade between your thumb and forefinger just above the handle
Wrap remaining fingers around the handle
This gives you maximum control and precision

The Handle Grip (For Tougher Jobs)

Wrap all fingers around the handle
Use when more force is needed (like cutting hard vegetables)
Offers more power but less precision

Your other hand is equally important—it’s the “guide hand” that holds the food:

The Claw Grip

Curl fingertips under, creating a “bear claw” shape
Use knuckles as a guide for the knife blade
Thumb and pinky grip the sides of the food for stability

This keeps your fingertips safely away from the blade while providing stability and control.

Essential Cutting Techniques

Master these five techniques and you’ll handle 90% of recipe requirements with confidence:

1. The Slice

Motion: Smooth forward motion with slight downward pressure
Best for: Larger items like cucumbers, cooked meats
Technique: Start with knife tip on board, draw backward slightly, then push forward and down
Goal: Even slices of consistent thickness

2. The Chop

Motion: Up and down movement, keeping the tip of the knife on the board
Best for: Herbs, garlic, smaller quantities
Technique: Use a rocking motion, pivoting around the knife tip
Goal: Finely cut pieces, size depending on recipe needs

3. The Dice

Motion: Systematic series of cuts to create cubes
Best for: Onions, peppers, potatoes, carrots
Technique:

Slice item into planks
Cut planks into sticks
Cut sticks into cubes

Goal: Uniform cubes for even cooking

4. The Mince

Motion: Rapid chopping with rocking motion
Best for: Garlic, ginger, herbs
Technique: Chop roughly first, then rock knife back and forth over ingredients
Goal: Very fine, almost paste-like consistency

5. The Julienne

Motion: Precise slicing into thin matchsticks
Best for: Carrots, peppers, courgettes
Technique:

Square off the ingredient
Slice thinly lengthwise
Stack slices and cut into thin strips

Goal: Thin, uniform strips for stir-fries or garnishes

Tackling Common Ingredients

Let’s apply these techniques to some ingredients you’ll prepare frequently:

Onions: The Foundation of Flavor

Halve the onion from root to tip
Peel off the skin
Place flat side down for stability
Make horizontal cuts toward the root (but not through it)
Make vertical cuts from top to root (again, not through it)
Slice across these cuts for a perfect dice

Garlic: The Aromatic Essential

Separate a clove from the bulb
Place flat side of knife on clove and press firmly to crush
Peel away skin (it should come off easily after crushing)
Mince by rocking knife back and forth over the clove

Bell Peppers: Without the Seeds

Cut off top and bottom
Stand pepper upright and slice down one side
Unroll the pepper and lay flat
Remove white ribs and seeds
Cut as needed (julienne or dice)

Herbs: Keeping the Flavor

Remove leaves from tough stems (for herbs like parsley, coriander)
Stack leaves together
Roll into a tight bundle (like a cigar)
Slice thinly across the roll for a chiffonade
Rock knife over slices for a finer chop if needed

Knife Care and Maintenance

A well-maintained knife is safer, more effective, and will last decades. Here’s how to care for yours:

Cleaning

Hand wash only: Never put good knives in the dishwasher
Wash immediately after use, especially after cutting acidic foods
Dry thoroughly before storing to prevent rust

Storage

Knife block: Keeps edges protected and accessible
Magnetic strip: Good for small spaces, keeps knives visible
Blade guards: Affordable option for drawer storage
Never store loose in a drawer (dangerous and damages edges)

Sharpening

Honing rod: Use before each cooking session to realign the edge
Sharpening stone: For actual resharpening (every few months)
Professional sharpening: Good option if you’re not comfortable doing it yourself

Signs Your Knife Needs Sharpening

Struggles to slice through a tomato skin
Slips off onion skin instead of cutting through
Requires more pressure than usual to cut

Food Preparation Workflow

Efficient food prep isn’t just about knife skills—it’s about workflow:

The Prep Sequence

Read recipe completely before starting
Gather all ingredients (mise en place)
Prep ingredients in order of stability:

Ingredients that won’t discolor or dry out first
Delicate herbs and easily oxidized items last

Group similar cuts together to minimize knife switching
Create a “done” area for completed ingredients

Prep Containers

Invest in a set of small bowls or containers to hold prepped ingredients. This keeps your cutting board clear and helps you stay organized.

Real-Life Application

Meet Tom, who used to avoid recipes that required more than minimal chopping. After learning proper knife skills:

Before: Spent 25 minutes haphazardly cutting vegetables for a stir-fry, with pieces of wildly different sizes that cooked unevenly
After: Completed the same prep in 10 minutes with uniform pieces that cooked perfectly

The result? His meal prep time decreased by 40%, his dishes cooked more evenly, and he actually started to enjoy the rhythmic process of chopping. As Tom put it, “I used to see prep work as a chore. Now it’s almost meditative—and my stir-fries actually cook properly!”

Quick Quiz: Test Your Understanding

When using a chef’s knife for most cutting tasks, you should hold it using:

The handle grip with all fingers wrapped around the handle
The pinch grip with thumb and forefinger on the blade
One finger on the spine of the knife for guidance
Any grip that feels comfortable

The “claw grip” technique refers to:

A way to hold the knife for more power
A method for sharpening knives
How to position your guide hand to protect your fingertips
A special cutting technique for meat

To dice an onion efficiently, you should:

Make random cuts until pieces look small enough
Make horizontal cuts, then vertical cuts, then slice across
Slice thinly, then chop the slices
Grate the onion instead of using a knife

Which of these is a sign that your knife needs sharpening?

It cuts through a tomato skin easily
It has a slight discoloration on the blade
It requires more pressure than usual to cut
It feels heavy in your hand

When preparing multiple ingredients for a recipe, you should:

Prep ingredients in the order they appear in the recipe
Always start with the hardest ingredients first
Prep ingredients that won’t discolor first, leaving delicate items for last
Prep all ingredients simultaneously to save time

Wrapping Up

Good knife skills are the foundation of efficient, enjoyable cooking. With practice, the techniques we’ve covered will become second nature, transforming your preparation from a chore to a satisfying part of the cooking process.

Remember that developing these skills takes time. Start slowly, focusing on safety and consistency rather than speed. As you become more comfortable, your speed will naturally increase.

In our next lesson, we’ll explore understanding recipes and measurements—how to decode cooking instructions and ensure your ingredients are properly measured for success. Until then, practice your cutting techniques on different vegetables and fruits, paying attention to consistency and safety.
