Okay, my camera is still having a little trouble, so I don’t have any new cooking/baking posts to bring you. But today I’m going to talk about knives. One thing I’ve noticed when dealing with people who don’t cook a lot or aren’t comfortable cooking is a tendency to use the wrong knife for a job. More often than not, it seems, people are afraid to use a knife big enough for the job they’re trying to do. I’ve seen lots of people chopping celery with a small serrated knife or trying to slice a 3″ potatoe with a 2 1/2″ paring knife.
As a general rule (note, this doesn’t ALWAYS apply), you want to use as big of a knife as is practical for your needs. Obviously, you don’t want to use an 8″ chef’s knife for peeling peaches, but generally speaking, bigger is better. The main reason is that a bigger knife allows your knife hand (the hand in which you are holding the knife) to stay further away from the food which you are cutting/chopping/etc. By distancing your knife hand from your food and your food hand, you bring less clutter to the area in which you are cutting. This results not only in a much safer cut, but also allows you to see what you are doing more easily, and thus perform a better cut. So while many people seem to be afraid of a big knife, in reality, a small knife doing the wrong job is often much more dangerous.
So now we’ll look at a few common types of knives and their uses:
Chef’s Knife
The Chef’s Knife is a “cousin” of the famous “butcher’s knife.” Butcher’s knives aren’t actually commonplace anymore, as few people truly butcher their own meat. The chef’s knife, however, is a slightly toned-down version of the butcher knife. The chef’s knife is more practical than the original butcher’s knife for common tasks. With it’s long, heavy, slightly curved blade the chef’s knife is perfect for chopping, dicing, and mincing. Additionally, as it is usually the largest knife in an average kitchen, it is the best suited knife (in most people’s repertoire) for cutting large cuts of meat.
To properly chop/dice/mince with a chef’s knife, the tip of the blade should never leave the cutting surface. Rather than picking the knife up and chopping straight down to make each cut, leave the tip on the cutting surface and move the knife in a lever-like action, moving the food under the knife (rather than moving the knife to the food) with each cut. This also is a much safer method than picking the knife up off the cutting board after each cut. Also, with it’s deep blade (note how the blade is much “higher” than the handle – that is, the cutting surface of the blade is below the handle, not in line with it as on a paring knife), this allows the user to keep a firm grip on the knife with each cut.
Boning Knife
The boning knife should be (but usually isn’t) one of the least used knives in most kitches. With it’s long, narrow, curved-only-at-the-tip blade, it’s intended for removing bones from poultry and meat. The narrow blade allows the knife to be turned sharply around bones. Because of it’s narrow blade, it’s not practical for chopping vegetables because the operator’s hand doesn’t have any clearance when the blade is pressed against the surface. The boning knife can be used for slicing things such as tomatoes which don’t take well to a true chopping action when a serrated knife is not available.
In the absence of a true filet knife (most people don’t have filet knives) the boning knife is the best option for fileting fish as its generally flat blade (as compared to the chef’s knife) can slide between the skin and meat of a fish with ease.
Paring Knife
A paring knife is a small (usually a 2 1/2″ to 4″ blade), generally straight-bladed knife used for, well, paring… Of course, while most people know what a paring knife is, they don’t think about what “paring knife” means. To pare means to get rid of an outside, excess, or irregular part. In other words, this knife is primarily to be used for peeling. The paring knife is the most improperly used knife in most people’s draw (or block). The paring knife is to be used for jobs when a larger knife simply won’t cut it. Peeling a potato or cutting the seeds out of a jalapeno are jobs that can only be properly done with a very small, thin-bladed knife.
Too many people, however, use the paring knife for chores much bigger than it was intended to tackle, such as chopping or slicing. And paring knives don’t handle big jobs well.
Serrated (Bread) Knife
Many people have tried to slice a loaf of bread with a regular knife only to end up squashing the loaf before they can break through the crust. This is where a serrated knife comes in. This knife is primarily used for slicing (bread, tomatoes, etc.). It’s serrated edges are designed for easily breaking through soft (squishable) foods without requiring much force. Serrated blades are also useful for slciing things such as a ham or a roast. Serrated blades are not intended to chop with. I know several people who own almost exclusively serrated blades and use them for every purpose.
Because of their design, serrated blades will dull much more quickly than a straight blade, and are much harder to properly sharpen (which will be a post for another day). Instead of spreading the pressure evenly across the whole blade, when a serrated blade comes into contact with a hard surface, only a few points (teeth) will touch. This creates a much higher pressure on each blade, dulling it much faster. When a serrated blade becomes dull, it becomes even more ill-suited for its designed task than a traditional blade.
The main thing to take away from this is to not be afraid of a knife. When used for it’s proper purpose, a good knife will make your job much much easier, and therefore much safer. Using the wrong knife for the wrong task, however, not only makes cooking unsafe, it also makes it more difficult – and less fun.
