The pot was invented 10,000 years ago, and a simmering one has been a symbol of a well-tended hearth ever since. I don’t mean to suggest that now that you have been reminded of the age and goodness of a pot of water, you start boiling everything in your kitchen — but that instead of trying to figure out what to do about dinner, you put a big pot of water on the stove, light the burner under it, and only when it’s on its way to getting good and hot start looking for things to put in it.
In that act, you will have plopped yourself smack in the middle of cooking a meal. And there you’ll be, having retrieved a pot, filled it, and lit a burner, jostled by your own will a few steps farther down the path toward dinner.
There are as many ideas about how to best boil water as there are about how to cure hiccups. Some people say you must use cold water, explaining that hot water sits in the pipes, daring bacteria to inoculate it; others say to use hot, arguing that only a fool wouldn’t get a head start. Debates rage as to whether olive oil added to water serves any purpose. (It only does if you are planning to serve the water as soup, which you may, but it makes sense to wait to add the oil until you decide.)
Potatoes should be started in cold water, as should eggs. But sometimes I find myself distractedly adding them to water that’s already boiling, and both turn out fine. Green and leafy vegetables should be dropped at the last second into a bubble as big as your fist. Pasta, similarly, should only be added when a pot is rollicking, and stirred once or twice.
Ecclesiastical writers on the subject point out that in the beginning there was water, all life proceeded from water, there was water in Eden, water when we fell, then the slate got cleaned with it. Water breaks, and out we come.
The point, as far as I can tell, is that water has been at it, oblivious to our observations of it, for longer than we know.
I recommend heating up a great deal of it, covered if you’re in a rush, because it will boil faster that way, or uncovered if you need time to figure out what you want to boil. As long as it’s a big pot and the water in it gets hot, whichever technique you choose and however you time your addition of ingredients, the world, which began by some assessments with a lot of water at a rolling boil, will not come to an end.
Julia Child instructs tasting water periodically as it climbs toward 212 degrees to get used to its temperature at each stage. Her advice might be overzealous, but it teaches an invaluable lesson, not about boiling, but about learning to cook: If there is anything that you can learn from what is happening, learn it. You don’t need to know how the properties of water differ at 100 degrees and at 180, but by tasting it at those temperatures you may learn something about your pot or your stove, or the spoon you like best for tasting.
Once your water reaches a boil, salt it well. The best comparison I can make is to pleasant seawater. The water needs to be this salty whether it’s going to have pasta cooked in it or the most tender spring peas. It must be salted until it tastes good because what you’re doing isn’t just boiling an ingredient, but cooking one thing that tastes good in another, which requires that they both taste like something.
All ingredients need salt. The noodle or tender spring pea would be narcissistic to imagine it already contained within its cell walls all the perfection it would ever need. We seem, too, to fear that we are failures at being tender and springy if we need to be seasoned. It’s not so: It doesn’t reflect badly on pea or person that either needs help to be most itself.
Add salt by hand so that you start to get a feel for how much it takes, and as you do, taste the water repeatedly. This may at first feel ridiculous, and then it will start to seem so useful you’ll stand by the pot feeling quite ingenious. Even though the water is boiling you can test it with your finger. If it’s well seasoned, just tapping the surface will leave enough on your skin for you to taste.
When you find yourself tasting your water, you are doing the most important thing you ever can as a cook: The only way to make anything you’re cooking taste good, whether it’s water or something more substantial, is to make sure all its parts taste good along the way. There are moments in cooking when common sense dictates not to taste — biting into a dirty beet or raw potato — but taste anything else from a few minutes after you start cooking it until it’s done. You don’t need to know what it’s supposed to taste like: What anything is supposed to taste like, at any point in its cooking, is good. This is as true for water as for other ingredients.
Boiling has a bad name, and steaming a good one, but I categorically prefer boiling.
We think we’re being bullish with vegetables by putting them in water when we’re actually being gentle. There may be nothing better than the first tiny spring potatoes and turnips, their pert greens still attached, or the first baby cabbages, thickly wedged, all boiled.
Salted water seasons the vegetable, which means that by the time it comes out, it is already partially sauced. Additionally, boiling a vegetable improves the water as much as it does the vegetable. Water you’ve cooked cabbage in is better for making cabbage soup than plain water would be, and it’s easier than making chicken stock.
The best vegetables to boil will be the ones in season. They will also be the ones with the most leaves, most stalks, longest stems. Knowing that you can simply boil the expensive, leafier vegetables at the farmers’ market should help justify your buying them. All you have to do is cut them up and drop them in water, and you can drop all of them in water.
When you go hunting for vegetables for your boiling pot, don’t be deterred by those stems and leaves. Though it’s easy to forget, leaves and stalks are parts of a vegetable, not obstacles to it. The same is true for the fat and bones of animals, but I’m happy to leave that for now. You can cook them all.
We most regularly boil broccoli. If you do so obligatorily, I want to defend it. If you don’t do it, because you’ve always held boiling in contempt, I suggest you buy a head of broccoli that is dark jade green, stalky, and bold; and while you’re at it, one of cauliflower, whole, with light, leafy greens still attached; and boil each on its own. If only withered, mummified versions of either are available, they can be improved by slow stewing with olive oil, garlic, and lemon peel, but for boiling, only the best will do.
A Recipe
Salsa verde is what’s served with Italian boiled meals. It’s the best accompaniment to boiled meat, and among the best accompaniments to anything. This is a simple one.
Salsa Verde
1 shallot, finely chopped
1/2 tsp. salt
red or white wine vinegar
1 bunch parsley, leaves picked from stems and roughly chopped
1/2 clove garlic, chopped and pounded to a paste with a tiny bit of salt in a mortar with a pestle or on a cutting board
1 anchovy fillet, finely chopped
1 tsp. capers, finely chopped
1/2 cup olive oil
Put the shallot in a small mixing bowl.
Add the salt and then enough vinegar to cover. Let it sit for 10 to 15 minutes.
Drain the shallot of its vinegar, reserving it for a future vinaigrette.
Mix the shallot and the rest of the ingredients together.
