The reason beginners struggle with seasoning is often not that they can’t tell if food is salty enough. It’s that many people think of seasoning as something that happens at the end. You make a dish, taste it once, and then you sprinkle some salt and pepper, hoping it all magically comes together. But that doesn’t work very well. The best dishes are seasoned throughout the cooking process, because they need the ingredients to cook together, lose water, concentrate in flavor, and change texture. Whether it’s tomato sauce, a pan of mushrooms or simple soup, the salt needs time to develop alongside these changes. When you start seasoning earlier, the dish will start tasting more intentional.
There’s no easier way to practice this than with a basic recipe that changes as you cook it. Take a pot of soup full of vegetables, or rice with soft carrots and onions. Add a small amount of salt when you add the onions to the pan or start cooking. Taste again after you add liquid. Taste again after all the liquid cooks down. You should not be adding more salt every time you taste, though. You should just be thinking about what happened to the dish while it cooked and how it developed. Often, you will only be tasting the broth, the sauce or the surface liquid. Instead, you need to eat a spoonful containing both liquid and solids, because you want to make sure the whole bite is evenly seasoned.
Some people also tend to think only of salt and pepper when they’re seasoning. But when you start to think in terms of contrast, seasoning becomes more controllable. A soup can certainly need salt, but it might also use a little more acidity to add brightness, caramelized onions for depth, a generous helping of black pepper for heat or soft butter or olive oil for mellowing. You won’t solve a boring soup with more salt alone. You’ll actually need to give it a squeeze of lemon to wake it up. Sometimes, a roasted dish might taste like it has been overcooked and needs a bit of acidity to balance. Sometimes something is just too spicy, and you can help it by adding a little fat to round it out. It’s all too common to find a beginner just adding a little more salt or pepper whenever the dish is off-balance. The first thing you should do is step back and decide what you think is missing. Does it need more intensity, acidity, sweetness or fat? Just one of those questions can completely change the dish.
One easy way to teach yourself this skill without wasting any food is to cook a small recipe for a few minutes and divide it into three separate bowls. Try a small pot of plain rice, or maybe a few minutes of simmered vegetable soup. Leave one as is. Add some salt to the second one. Add a little salt and lemon to the third one. Try a small spoonful from each and then compare them. Don’t just have one taste and then judge it; instead, taste from each one, go back and forth and compare the taste from every single bowl. This way you can actually hear what’s missing from each one and you can get a sense of what is improving the dish and what is not doing much or maybe making it worse. This exercise can help you learn to think of contrast rather than just salt and pepper as tools you need to make a good dish.
Another common problem is knowing what to do when you’ve added too much salt. Sometimes, you have to throw everything out. Sometimes there’s still hope. When you’re working with a soup or sauce, it can be possible to add more of the unsalted parts to dilute the dish. If your sautéed vegetables ended up over-seasoned, just fold them into rice or beans to cut the intensity. If something tastes a little too hot or sharp but is still savory, just add more fat or acidity to smooth it out. The main thing is to stay calm and only make one change to the dish at a time. If you just try to make a few changes at once, it can be impossible to know whether or not you actually fixed the dish.
Eventually, this will become a lot easier, as long as tasting is a habit, rather than an event. In just a few weeks of cooking a few recipes and trying to taste a little more, you’ll start knowing when it’s time to add a pinch of salt to soften some onions or when a stew needs a little bit more lemon or when the flavor is starting to come together in the pan, rather than just on your tongue. This will help you make the right choices for a dish before it’s actually plated and served. Good flavor never just happens at the end. It takes time, effort and attention to actually get there.
