Beans : To Soak or Not to Soak, It's No Longer a Question


Almost every recipe in every cookbook you've ever read says you must soak dried beans before you cook them. In almost every case that advice is wrong.

Letting dried beans sit overnight in a bowl of cold water does nothing to improve their flavor or their texture. In fact, it does quite the opposite. While soaking shortens the unattended cooking time of beans somewhat, the time saved is marginal and there are no other labor-saving benefits. Finally, soaking does absolutely nothing to reduce the gas-producing properties of beans.

These may be difficult ideas to get used to, flying as they do in the face of everything most of us have been taught about cooking beans. One friend, an Arizonan, dismissed the idea out-of-hand, attributing it to my New Mexican background. "What do they know about beans?" she said.

But cooking unsoaked beans is not new. No less an authority than noted Mexican cookbook writer Diana Kennedy has advocated it for years. "If you want the best-flavored beans, don't soak them overnight, but start cooking in hot water," she says in "The Cuisines of Mexico" (Harper & Row: 1972).

Recipe Correction--In last week's story, "Spilling the Beans," an incorrect ingredient was listed in the recipe, Boston baked beans, adapted from "Jasper White's Cooking From New England" (Harper & Row: 1989). Dried mustard should be used, rather than prepared mustard.
1 pound navy beans, pea beans or other small dried white beans
1/2 pound salt pork
1 medium onion, cut in 1/2-inch dice
4 cloves garlic, finely chopped
1 cup tomato puree
1 teaspoon salt
2 teaspoons freshly ground black pepper
1/4 cup dry mustard
1/3 cup maple sugar
1/3 cup molasses
2 bay leaves
3 tablespoons cider vinegar
Sort through beans and discard off-colored or broken ones. Rinse and drain beans. Set aside.
Remove rind from half of salt pork. Cut into 1/2-inch squares. Cut other half into 3/4- to 1-inch-thick strips to equal 4 or 5 strips, with rind attached. Set aside.
Line bottom of earthenware crock or bean pot with 1/2-inch squares of salt pork and onion. Place beans on top.
Bring 1 quart water to boil in saucepan. Add garlic, tomato puree, salt, pepper, dried mustard, maple sugar, molasses, bay leaves and vinegar. Simmer 1 minute. Mix well and pour over beans.
Score strips of salt pork crosswise, about every inch, without cutting through. This prevents strips from curling while cooking. Place strips on top of beans and liquid. Cover pot and bake at 250 degrees 5 hours, checking occasionally (first at 2 hours, then every hour), to be sure liquid is just barely covering beans. Add more water as needed.
After 5 hours, remove cover of bean pot and cook 1 hour more. Remove strips of salt pork and stir pot before serving. Makes 6 to 8 servings.

In fact, the more I asked around, the more people I found who cooked beans this way--mostly, it seemed, people from Mexican or Central American families--although at least one prominent New American chef and another well-known French chef agreed.

What's more, few commercial canners soak dried beans before cooking. In fact, in a way they don't cook the beans at all. The heat and pressure of the canning process (called the retort) is enough to cook--perhaps even overcook--the beans right in the can.


Still, I wanted to see for myself. Call it trial by frijoles.

First, I cooked three pots of beans: one soaked overnight, one quick-soaked (brought to a boil and left to sit, covered for one hour), and one simply covered with boiling water. To each pot I added a hunk of salt pork, some sliced onion and a bit of garlic. I simmered them slowly on top of the stove, covered.

The two soaked beans did cook more quickly than the unsoaked--they were finished in about 1 hour and 15 minutes, as opposed to two hours. But when I sampled them, the extra 45 minutes paid off. The two pots of soaked beans were pallid compared to the unsoaked (though the long-soaked were better than the quick-soaked). The unsoaked beans had a noticeably deeper flavor; they were firmer to the bite, and they did not break up as much in cooking.

Then came the ultimate test. I sat down with a big bowl of the cooked unsoaked beans (after a little refrying with bacon and a handful of grated Monterey Jack cheese) and ate lunch. I waited, half expecting to blow up like a balloon (as a precaution, I did this test at home, alone). Nothing untoward happened.

That experiment was far from scientific, but after talking to a couple of researchers who confirmed my results, I moved on to more phone calls and other tests.


All of us, it seems, have our own set of folk tales about cooking beans. And most rules are followed simply because that's the way someone told us to do it, rather than as a result of any kind of testing.

* Some people told me quite firmly that beans should never be salted before cooking--that this keeps them from softening during cooking. In fact, Kennedy herself makes this claim.

So I cooked beans with salt added (1 teaspoon per pound of beans turns out to be about the right ratio) and without. They cooked to exactly the same degree of softness in almost exactly the same time.

Interestingly, though, to get the same level of saltiness in the unsalted batch of beans, I had to add more than twice as much salt. And even then, it was more a case of the broth being salty than the beans.

* Other people said that the type of pot in which beans are cooked is the most important thing--only earthenware will do.

I cooked beans in three different pots--earthenware, stainless-steel and unlined aluminum. There was some difference in the rate at which the beans soaked up water (or, probably more accurately, the pans soaked up water). The earthenware needed more water early but then seemed to maintain a steady level a little better. I could find little difference in flavor between the earthenware and the stainless-steel, but the unlined aluminum lent a distinctly metallic flavor to the beans.

* One chef told me he never allowed his beans to be cooked on top of the stove. Only by cooking them in the oven is it possible to get the slow, steady pace they need, he claimed.


I cooked beans both on top of the stove and in the oven. With constant attention and a ready flame-tamer, I could manipulate the temperature well enough to keep the beans at a sufficiently slow simmer. But, covered, in a 250-degree oven, the cooking was almost effortless. All I had to do was check every half-hour or so to make sure there was sufficient water.
