Beans from Scratch — Why the Can Is Underrated and the Pot Is Better

The case

A can of decent beans costs $1.50-$3 in the US. A pound of dry beans costs $2-$5 and produces three cans worth of cooked beans plus three to four cups of bean broth. The broth — sometimes called pot likker in the American South or aquafaba when it's chickpea-specific — is itself a valuable ingredient. The math is in favor of dry beans.

The bigger argument is flavor. Canned beans are pressure-cooked at high temperature with citric acid or calcium chloride preservatives. They are functional. Home-cooked beans, slow-simmered with aromatics, are something else — a different category of food. Once you've eaten one bowl of properly cooked home beans, you'll resent canned for at least a year.

The basic method (4-6 servings)

Ingredients

1 lb (450g) dry beans (pintos, black, cannellini, cranberry, chickpeas, anything reasonable)
1 onion, halved
4 garlic cloves, peeled, smashed
1 bay leaf
1 small dried chile (optional, for heat)
2 tsp salt (added near the end)
2 tbsp olive oil or 1 small chunk salt pork (optional)

Method

Sort and rinse. Spread the beans on a plate. Look for stones, broken beans, debris. Rinse in a colander.
Soak. Overnight in plenty of cold water. Or: bring beans to a boil for 2 minutes, then turn off heat and let sit 1 hour (quick-soak method).
Drain and re-cover. Discard soaking water. Put beans in a heavy pot, cover with fresh water by 2 inches.
Aromatics. Add onion halves, garlic, bay leaf, dried chile (if using), olive oil or salt pork.
Simmer. Bring to boil; immediately reduce to bare simmer. Cover loosely. Cook 1 to 2 hours depending on variety and age of beans.
Salt near the end. Add salt in the last 20-30 minutes. Older convention said salting too early toughens beans; modern testing finds the effect is small but the timing-near-end is still a useful habit because it lets you taste and adjust.
Done when creamy. A finished bean is fully soft but still holds its shape. Test by squashing one between your tongue and the roof of your mouth.

Pro tips

Soak with baking soda for chickpeas. A pinch (¼ tsp per pound) softens skins and produces creamier results.
A piece of kombu in the pot reduces beans' raffinose content (the FODMAP that causes the famous gas) noticeably. Pull it out before serving.
Skim foam off the surface in the first 20 minutes; the bean foam can give a slightly metallic flavor if left.
Save the broth. Drain finished beans over a measuring cup. The broth is a flavor base for soup, for cooking rice, for thinning a stew.

Beans worth knowing

Rancho Gordo — the Napa-based heirloom bean importer. Their beans cost more per pound but are genuinely better. The Royal Corona, Domingo Rojo, and Christmas Lima are worth seeking out.
Camellia — the New Orleans red bean brand. Pinto and red beans done well.
Goya — affordable, available, fine.
Anson Mills heirloom field peas — Lowcountry cowpeas in their heritage varieties. Sea Island red pea is particularly good.

What to make with one pot of beans

Day 1: Hot beans with rice and a fried egg.
Day 2: Beans with greens (mustard, kale, collards), olive oil, toast.
Day 3: Bean soup (mash some beans into the broth, add carrots and celery, top with parsley).
Day 4: Beans pureed into a dip with garlic and olive oil; serve with bread.

The canned vs from-scratch question

Canned beans are one of the better industrial food products.
The processing — beans cooked in salted water, then sealed
under pressure — produces a final product that is reasonably
close to home-cooked. The fiber, protein, and bulk nutrients
survive the processing intact. The texture is acceptable.

The cost: roughly 1 dollar per can in the US, which yields
roughly 1.5 cups of cooked beans. The per-cup cost is roughly
70 cents.

Beans from scratch (dried, soaked, simmered) cost roughly 0.20
to 0.30 dollars per cup of finished beans. The cost saving is
real but modest at single-family scale.

What from-scratch gives you that canned does not

The argument for from-scratch beans is not primarily about
cost. It is about flavor, texture, and the bean cooking liquid
that the canning process discards.

Specifically:

Bean broth. The liquid in which beans are cooked is rich,
starchy, and savory. It is the base for the best bean
soups, the right deglaze for vegetable preparations, and a
legitimate replacement for vegetable stock in many
applications. Canned beans come in a thin, watery brine that
does not function the same way.
Texture control. Home-cooked beans can be cooked to
exactly the texture you want — slightly al dente for
salads, completely soft for purées. Canned beans are at the
pre-set canning texture.
Seasoning integration. Beans cooked with a bay leaf, a
smashed garlic clove, an onion half, a chunk of pancetta or
parmesan rind, and salt at the right time absorb those
seasonings throughout. Canned beans are seasoned with salt
only.
Variety. Dried beans come in dozens of cultivars from
the heirloom growers (Rancho Gordo, Tierra Vegetables,
Anson Mills); canned beans come in 4 to 6 common
industrial varieties.

The technique

The basic from-scratch bean method:

Soak overnight (or quick-soak: cover with water, bring
to boil, off heat 1 hour). Drain.
Cook in fresh water with a bay leaf, a half-onion, two
smashed garlic cloves, optional parmesan rind or smoked
meat. Bring to bare simmer; cook 1 to 2.5 hours depending
on bean variety and age.
Salt in the last 30 minutes. Earlier salt can prevent
the beans from fully softening.
Cool the beans in their broth. They absorb the broth
and become more flavorful.

The total elapsed time is 12 to 14 hours (mostly soak time);
the active time is 15 minutes.

When canned is the right choice

Canned beans are the right choice when:

The dish is fast (under 30 minutes).
The beans are not the star (a quick chili, a topping for
toast, a fast salad).
You did not plan ahead (the soak step was forgotten).

In these cases canned beans get the job done. The dish does
not need from-scratch beans to be good.

When from-scratch matters

From-scratch beans matter when:

The beans are central (a pot of beans as the dinner; the
bean soup; the cassoulet).
The bean broth will be used (any application where the
bean cooking liquid contributes).
The texture must be specific (al-dente beans for a salad;
completely soft beans for a purée).
The bean variety matters (heirloom varieties from Rancho
Gordo or similar).

Sourcing dried beans

Rancho Gordo (rural Northern California) is the most-cited US
heirloom bean producer. Their catalog includes dozens of bean
varieties — most never seen in supermarkets. The price is
roughly 6 to 10 dollars per pound, which yields 2.5 to 3 pounds
of cooked beans.

Other producers: Tierra Vegetables (California), Anson Mills
(South Carolina, primarily grain but some beans), Native Seed
Search (Arizona, with Indigenous-American varieties), and
various smaller farmers-market growers.
