Where this sits on the food shopping list

Lentils are the legume that makes the rest of the bean bucket look slow: no soak, 20 to 30 minutes in the pot, 1,600 calories and over 100 grams of protein a pound, and up to 5 years in a sealed container with longer in Mylar. They are the protein for the first week of an outage, when fuel is short and nobody soaked anything the night before, and they belong in the bag for the same reason.

Which to buy

Brown and green lentils hold their shape and are the all-purpose ones; red and yellow lentils are split, cook in 15 minutes, and fall apart into a thick soup, which is what you want for dal and for thickening. Black (beluga) and French green lentils are firmer and cost more. Buy the brown ones in bulk for the store and keep a bag of red for the fast meals. Sort a handful for small stones before cooking; bulk lentils carry a few.

How to store it

Cool, dark and dry, in something airtight. The original bag or box is fine for the months you will use it in; for the years, the answer is the same as for rice: a Mylar bag with an oxygen absorber inside a food-grade bucket, which keeps out oxygen, moisture, light and every insect egg that came home from the mill. The Mylar ranking says which foods take an absorber and which do not.

A 5 gallon bucket holds about 33 pounds of lentils. They take an absorber. Old lentils cook a little slower; they do not go hard the way old beans do.

How to tell it has turned

Dry, clean-smelling lentils are fine at any age. Mold, webbing, small beetles or a musty smell mean the bag goes. Faded color is age. A few tiny stones are normal in bulk lentils and the reason to spread a handful on a plate before cooking.

Keep it

Faded lentils that are dry and odorless; lentils years past the date.

Discard on sight

Mold, a musty smell, webbing or insects.

How much, and how to use it

A cup of dry lentils makes about two and a half cups cooked and feeds three; plan on a pound per person per week in the first weeks. Rinse, cover with three cups of water per cup of lentils, simmer 20 to 30 minutes (15 for red), salt at the end. Lentils with rice is a complete protein and a meal on its own; lentils with a can of tomatoes and a spoon of curry powder is dal; a handful thickens any soup. They sprout in a jar in two to three days for a green vegetable in winter.

When the power goes out

The outage legume. Twenty minutes on a camp stove, or a five minute boil and 40 minutes in a wrapped pot or thermal cooker, with no soak and no planning. Red lentils are faster still.

Shelf-life figures are from the Survival Foods field guide; fridge, freezer and pantry times are from the USDA cold and pantry storage charts. Run the look, smell, taste check before eating anything past its date.

Questions this answers

Tap a question for the short answer.

How long does lentils last?

Lentils really last up to 5 years when kept airtight and cool, compared with the 2 to 3 years a label date typically gives. Watch for mold and pests as they age.

How do I store lentils long term?

Airtight, cool and dark; Mylar with an absorber inside a bucket for the years. About 33 pounds fills a 5 gallon bucket.

How do I tell if lentils has gone bad?

Look for mold, pests or a musty smell. Soak and cook a small sample as a test: lentils that stay rock-hard after soaking and cooking, or that taste off, are past their useful life.

How long do lentils last?

Up to five years at full quality in an airtight container, against a label of 2 to 3, and many years sealed in Mylar with an oxygen absorber. Dry, clean lentils are edible long after.

How do I tell if lentils have gone bad?

Mold, a musty smell, webbing or insects. Faded color is age, and a few small stones in bulk lentils are normal.

Do lentils need to be soaked?

No. Rinse and simmer 20 to 30 minutes, 15 for red lentils, in three cups of water per cup of lentils.
