Here's a video that shows how to make the batonnet and the allumette cuts. These long and thin cuts also form the starting point for the dice cuts. For example, to make the small dice, you'd start with the allumette and just trim it down into cubes.

The word allumette is French for "matchstick," and these slender knife cuts are perfect for lending a touch of elegance to soups, salads and other vegetable preparations.
Keep Your Chef's Knife Sharp

Keeping your chef's knife sharp will make your job in the kitchen easier — and safer, too. That's because when you're using a dull knife you have to apply more pressure than you would with a sharper blade, making the knife more likely to slip.

Using a knife steel, also called a sharpening steel or honing steel, helps align the knife's edge so that it cuts smoothly and easily.
Basic Cooking Principles:
Basic Knife Cuts & ShapesWhy Are Good Knife Skills So Important?Even if you don't work in a commercial kitchen, developing your knife skills will help improve the quality of the food you cook. Here's how:
1. Uniform cooking times.
Large pieces of vegetables take longer to cook than smaller ones. So if you're sautéing carrots that are cut to different sizes and shapes, you'll either overcook the smaller pieces by the time the bigger ones are done, or you'll cook the smaller pieces properly but leave the bigger ones undercooked. Consistent cutting technique ensures your food is cooked to a uniform degree of doneness.
2. Enhanced visual appeal.
Again, it's the art part of the culinary arts. Of course, no one's going to take out a ruler and measure your knife cuts — unless you're in culinary school. But sloppy knife work makes for a sloppy-looking dish.
Skilled knife work indicates a cook who takes pride in their work and doesn't take shortcuts. It's a way of paying a compliment to whoever you're serving the dish to — saying to them, in effect, "You're worth the trouble."
See the individual summaries below for more information on each of the different knife cuts:
Mayonnaise Recipe
This basic mayonnaise makes a great sandwich spread, and it can also form the base for salad dressings such as Blue Cheese, Thousand Island and Ranch.
For more detailed instructions, see this illustratedtutorial on how to make mayonnaise.
Also, here's a tutorial on how to separate eggs.
A light, neutral-flavored oil like safflower, canola or soybean oil will give the best results, but any blended oil labeled "vegetable oil" or "salad oil" will do the trick.
Finally, it can't be said too often: For safety reasons, use pasteurized eggs for this and any other preparation that contains raw eggs.
Prep Time: 20 minutesTotal Time: 20 minutes
Ingredients:
3 egg yolks (for safety reasons, use pasteurized eggs) 1 pint vegetable oil 1 Tbsp plus 2 tsp white wine vinegar 2-3 tsp lemon juice 1 tsp Kosher salt, or to taste Pinch cayenne pepper (optional)
Preparation:
1. Let all your ingredients come to room temperature before you begin.
2. Using an electric hand mixer, stand mixer or a wire whisk, whip the egg yolks for a minute or two, until they're thoroughly beaten.
3. Add the 2 tsp vinegar and whisk for about half a minute. Then add the salt, and the cayenne if you're using it, and beat for another 30 seconds or so.
4. Now, with the mixer going full speed (or with your arm whisking as hard as it can) add the oil very slowly, as little as a drop at a time.
5. When the emulsion starts to form, you can add the oil more quickly, but keep it at a fairly moderate stream. Adding the oil too fast will break your mayonnaise.
6. When the emulsion thickens, add a teaspoon or so of vinegar to thin it out. Continue adding oil, stopping occasionally to add more vinegar if the mixture gets too thick.
7. Finish with the lemon juice, both to add a bit of tang as well as to achieve the right consistency.
8. Store unused portion in the refrigerator, where it should keep for a day or two.Makes 1 pint of mayonnaise.
omemade mayonnaise
Ingredients
2 egg yolks 12 fl oz (340 ml) of vegetable or olive oil
1 - tbsp of lemon juice or white wine vinegar
1 - 2 tsp of Dijon mustard
salt and pepper
Method1. In a large mixing bowl whisk together the egg yolks with a pinch of salt.2. Add one drop of oil to the egg yolks and whisk together with an electric whisk.
3. Continue to add one drop of oil at a time, whisking continuously until the mixture begins to blend together and thicken. The process is to add one drop of oil and then blend it in before adding the next drop. This will take several minutes.
4. After a quarter of the oil has been blended, add the lemon juice or vinegar and beat into the mixture.
5. Continue to whisk in the remaining oil, which you should be able to add a lot quicker by now, in a thin stream.
6. Once all the oil has been beaten in, add the mustard to give extra taste and season with salt and pepper.
7. If the mayonnaise is too thick, you can whisk in a few teaspoons of boiling water.
8. Chill the mayonnaise in the refrigerator before serving.
9. The mayonnaise may be stored in the refrigerator for 3 - 4 days in an airtight container or jar.

Mayonnaise in a blender
Ingredients
2 whole eggs 10 fl oz (285 ml) of vegetable or olive oil
1 tsp of white wine vinegar
1 tsp of dry English mustard powder
1 crushed clove of garlic
salt and pepper
Method1. Place the eggs into the blender or food processor, along with the mustard, garlic,
salt and pepper and blend together.2. Pour all of the oil into the blender in a steady stream whilst the machine is
operating, so that it is immediately whisked into the egg yolk mixture.
3. Switch off the machine and taste the mayonnaise. Add the vinegar and any extra seasoning to taste and whisk together one last time.
Garlic Mayonnaise (aioli)
Use the recipe above for homemade mayonnaise adding 3 - 6 crushed cloves of garlic to the beaten egg yolks and salt. Proceed as above.
Blue Cheese Mayonnaise
Using the above recipe for homemade mayonnaise, add 8 oz (225 g) of crumbled blue cheese into the mayonnaise at the end and mix well.
Spicy Mayonnaise
Using the top recipe for homemade mayonnaise, instead of 1 - 2 tsp of mustard, increase this to 1 tbsp and then add 1 tsp of Worcestershire sauce and a few drops of Tabasco.
How to Dice an OnionBy keeping the root end intact, this method ensures that you can quickly dice an entire onion without
creating a mess. Keep in mind that the more narrow your incisions, the finer the dice.
Step 1: Slice off the top of the onion, about ½ an inch into the surface.
Step 2: Rest the onion vertically, slice in half through the root end, and peel back the outer layer.
Step 3: Make vertical incisions down to the root end.
Step 4: Make horizontal incisions down to the root end.
Step 5: Dice the onion accordingly and repeat with the remaining half.
How to Mince GarlicThis method will allow you to quickly peel and mince garlic. By smashing the entire clove, you also
release the flavorful juices. Adding kosher salt and making a paste comes in handy when adding
garlic to a salad dressing or marinade.
Step 1: Smash the entire clove, skin on, with the sharp end of the blade pointed away from your body.
Step 2: Peel away skin, and run the knife through the garlic until it is finely and evenly chopped.
Step 3: Add a few pinches of kosher salt to work as an abrasive.
Step 4: Use pressure and the flat side of your knife to work the ingredients back and forth on the board, until the
mixture resembles the consistency of a paste.
How to Chop Fine HerbsThis process is actually defined as a “chiffonade.” For herbs which bruise easily (basil, sage, etc),
this method allows you to cleanly and delicately slice herbs without damaging their texture.
Step 1: Stack 6-8 leaves on top of one another.
Step 2: Carefully roll up the leaves starting from the root end up to the tip.
Step 3: Use a knife to finely chop the herbs, resulting in long, thin strips.
Of course, these are just the fundamentals. Master everything here, and we’ll move on to butchering
wild game in the near future.
Keep those knives sharp!
MMharpening Up on Knife Skillsby Jessica McGovern
About a month ago Tufts University Slow Foods Student Organization approached me to host
a skillshare at my apartment to discuss knives, I gladly obliged. The evening began with
some basics that included an overview of knives and knife skills and ended by using all of
those meticulously cut vegetables in a tasty vegetable and herb soup. Here are some of the
topics that we discussed:
Overview of Knives
You don't have to be a trained chef to produce a great meal. Knife skills are one of the
fundamental components to becoming an exceptional cook. Knives come in many shapes
and sizes, each having its own specific purpose. Many people become discouraged by all of
the different options that are available, but it really is not necessary to have more than the
four basic types of knives.
* Chef's Knife- The most versatile of all knives, with a wide blade that is 8" to 10" long. It is
best to choose a knife that feels good and balanced in your hand. The knife should have a
full tang (this means that the blade should go all the way through the handle for the best
wear and stability).
* Paring Knife- Paring knives are generally 2-1/2-4" in length. It is ideal for peeling and coring
fruits and vegetables, cutting small objects, slicing, and other hand tasks.
* Boning Knife- This type of knife has a more flexible blade to curve around meat and bone.
Generally 4-5" long.
* Bread Knife- Bread knives are usually serrated (having teeth like a saw). Most experts
recommend a serrated knife that has pointed serrations instead of wavy serrations for better
control and longer knife life. You must use a sawing motion when using a serrated knife.
Knife Cuts
The main point I stressed when discussing knife cuts was uniformity. If all of the pieces are
about the same size the vegetables will cook evenly. One of the best ways to learn, besides
doing, is by seeing. Check out this video by Bobby Flay to see how to cut red peppers and
garlic (his favorite).
Knife Safety Tips
1. Chop slowly and carefully.
2. Always cut away from your body.
3. Make sure your hands are dry.
4. Make sure that you curl your fingers under on the hand holding the food. This takes a
while to get used to, but will become second nature with practice. If your fingers are curled
under, the chances are good you will never cut yourself.
5. Watch what you're doing at all times.
6. Using your dominant hand, hold the knife firmly and using a rocking motion, cut through
the food. The knife should not leave the surface you're working on. Move your hand (with
the curled under fingers) along as the knife cuts the food.
7. Always make sure that your cutting board is secured and will not move while you are
cutting. Try placing a wet paper towel or dishrag underneath your board.
Sharpening and Truing
A chef once told me "a sharp knife is a happy knife." It's a little sentimental for my taste. I
prefer the saying "a sharp knife is a safe and efficient knife." Having a sharp knife ensures
that you have even cuts. Dull knives can become dangerous when you apply extra pressure
while pressing down on the knife, the extra pressure leads to less control. There are several
ways to sharpen your knife such as using a wet stone, a handheld sharpener and an electric
sharpener. Personally, I prefer the handheld sharpener because it is cheap, effective, light
and safe to use.
Another tool used to keep your knife sharp, but
it does not actually sharpen your knife, is called a truing steel. This long, round object keeps
knives sharper by straightening out the edge. To use a steel hold the knife in your dominant
hand and the steel in the other, with the steel point pressed into a solid waist-high surface.
Hold the knife base at the top of the steel at a 20 degree angle. Slowly draw the knife down
the length of the steel, pulling the knife back so the entire blade, from base to tip, moves
against the steel, as if you were slicing off pieces of the steel. Repeat on the other side. Do
this five or six times.
