A mysterious entrée in a subtly lit atmosphere.

In the kitchen, there’s no shortage of advice, tips, and “old wives’ tales” passed down through generations. While some may have a kernel of truth, many common cooking myths can lead to confusion, mistakes, and unnecessary stress. If you’ve ever been told to cook pasta with oil, or to use a dull knife because it’s safer, you’re not alone. In this article, we’ll debunk some of the most widespread cooking myths and help you separate fact from fiction, so you can cook with confidence.

1. Myth: Cooking Pasta with Oil Prevents It from Sticking

The Truth: Many people add oil to the water when cooking pasta, believing it will prevent the noodles from sticking. While it may seem like a good idea, this practice actually doesn’t do much for your pasta and can interfere with your sauce sticking to the noodles later.

Why It Doesn’t Work: Oil floats on the surface of the water, and because pasta is starchy, it tends to release some of that starch into the water, helping the noodles separate naturally. Adding oil only makes the surface slippery, which can cause your sauce to slide off.

What Really Works: Instead of oil, stir your pasta occasionally during the first few minutes of cooking to prevent sticking. Also, make sure to cook the pasta in a large pot with plenty of water.

2. Myth: You Should Always Salt Water Before Cooking Pasta

The Truth: It’s commonly recommended to add salt to your pasta water for flavor, but some people believe you should always add it right when the water starts boiling. However, timing matters when it comes to salting your pasta water.

Why It Doesn’t Work: If you add salt before the water is fully boiling, it can increase the boiling point of the water, which could slightly delay cooking. While this is minimal, it’s more effective to wait until the water is fully boiling before adding salt.

What Really Works: Salt your water when it reaches a rolling boil for the best flavor infusion into the pasta. Use about 1-2 tablespoons of salt per gallon of water.

3. Myth: A Dull Knife Is Safer than a Sharp Knife

The Truth: This myth has been around for a long time, but the idea that a dull knife is safer is just not true. In fact, a dull knife can be more dangerous than a sharp one because it requires more force to cut, making it more likely to slip and cause an injury.

Why It Doesn’t Work: Dull knives are harder to control and cause you to apply more pressure, which can result in accidents. A sharp knife, on the other hand, will cut through ingredients with minimal effort and is easier to maneuver.

What Really Works: Always keep your knives sharp. Regularly honing and occasionally sharpening your knives with a professional sharpening tool will ensure they perform safely and efficiently.

4. Myth: Adding Salt to Meat Makes It Dry

The Truth: This myth has caused many cooks to avoid salting meat ahead of time, fearing that it will draw out moisture and result in dry, tough meat. While it’s true that salt draws moisture, it actually helps the meat retain moisture during cooking.

Why It Doesn’t Work: When salt is applied to meat and given time to rest, it draws out moisture initially, but then the meat reabsorbs it along with the salt. This process enhances flavor and tenderness.

What Really Works: For the best results, salt your meat about 30 minutes to an hour before cooking. This allows the salt to permeate the meat and improve its flavor and moisture retention.

5. Myth: You Should Always Rinse Rice Before Cooking

The Truth: Rinsing rice is a common practice, but it’s not always necessary and depends on the type of rice you're cooking.

Why It Doesn’t Work: Some types of rice, like basmati, benefit from rinsing to remove excess starch, which can cause the rice to become gummy. However, for other types like risotto rice or sushi rice, rinsing isn’t always required.

What Really Works: For most white rice varieties, rinsing helps achieve a fluffy texture, but for varieties like risotto or sticky rice, it’s best to skip the rinse to preserve the desired texture. Check your recipe’s instructions for the best method.

6. Myth: You Should Always Use Fresh Herbs for Cooking

The Truth: Fresh herbs are fantastic for many dishes, but using dried herbs isn’t always a compromise. Dried herbs can actually enhance flavor in some dishes and are often more concentrated than fresh.

Why It Doesn’t Work: Fresh herbs may seem like the obvious choice for cooking, but they tend to lose their flavor quickly when exposed to heat for too long. Dried herbs retain their flavor longer and are perfect for slow-cooked dishes.

What Really Works: Use fresh herbs when you want a bright, fresh flavor, and opt for dried herbs in slow-cooked or long-simmering recipes where their flavor can infuse deeply into the dish.

7. Myth: Cooking Meat on High Heat Makes It More Tender

The Truth: While it might seem like high heat will seal in the juices and make meat tender, the opposite is often true.

Why It Doesn’t Work: High heat causes the proteins in meat to contract too quickly, resulting in a tough and dry texture. It also can cause meat to burn on the outside before it cooks through.

What Really Works: For tender meat, cook it over medium or low heat to allow it to cook through without overcooking or drying out. For slow-cooking cuts like brisket or stew meat, opt for low and slow cooking methods to break down collagen and achieve a tender result.

8. Myth: Cooking Vegetables with the Lid On Keeps Nutrients Intact

The Truth: While steaming vegetables with the lid on can help retain moisture, it may not necessarily preserve nutrients better than cooking without a lid.

Why It Doesn’t Work: When you cook vegetables with the lid on, they tend to steam in their own moisture, which can cause some nutrients (like vitamin C) to degrade. However, leaving the lid off can let nutrients escape into the steam.

What Really Works: To best preserve nutrients while cooking vegetables, try steaming with a minimal amount of water or blanching. If you need to cook with a lid, do so for a short period to keep the heat in without losing too many nutrients.

Cooking myths can often lead to frustration and wasted time in the kitchen. By understanding the facts behind common kitchen misconceptions, you can become a more confident and efficient cook. Keep these truths in mind as you cook, and you’ll soon see the difference in your dishes—from better pasta to juicier meat. Happy cooking!
