Welcome to the wonderful world of lentils

What are lentils?

Before we dive into the nutritional info and benefits of miniature legumes, let’s talk about what they are. These little lens-shaped seeds (which gives them their name), grow in pods, sometimes called pulses. They’re part of the same family as peas, beans and peanuts, and they come in a variety of colours, including yellow, red, green and black. Lentils are a common substitute for meat in veggie dishes and are a much-loved ingredient in India when used in curries and dals as a protein replacement.

Where do lentils come from?

Lentils originated in the Middle East and have been cultivated for thousands of years. They are one of the earliest crops domesticated by humans and were traditionally grown in regions like Europe, Asia and North Africa.

Different types of lentils

Lentils come in a rainbow of colours depending on where they’re grown. Their flavours vary across the board, from earthy and peppery; to lighter and sweeter finishes, so you can add your own seasoning to complement other ingredients.

Black lentils: These are sometimes called beluga lentils because they look a bit like beluga caviar when they’ve been cooked. They taste quite light, and some say they can detect a bit of a creaminess to them.

Green lentils: There are two kinds of green lentils, French and original. The standard ones are big and flat and work great as an accompaniment to a salad. While the French variety is much smaller with similar colouring to tiny watermelons.

Yellow lentils: The yellow lentils are nutty to taste and a little bit more complex than the red variety. They’re really popular in Middle Eastern dishes, used for the likes of purées, soups and stews.

Red lentils: This is actually yellow lentils in disguise – they’re what’s left after having been hulled and split. And because they’ve had their outer layer removed, they cook quicker.

Puy lentils: These grey-green lentils, cultivated in the French region of Le Puy, tend to be pricier than other commonly used varieties.

How to prepare and cook lentils

Despite the fact the lentil sits within the legume family, they don’t need to be soaked before cooking – just boil and simmer. So, once you’ve made your lentil decision, grab a few scoops, put them in a pan, bring them to a bubbling boil, and then turn the heat down to a simmer. Cover and let them absorb the liquid for around 30 minutes.

How long to cook lentils

As a rough guide, we would recommend the following:

  • Green and brown lentils: 35-45 minutes
  • Red split lentils: 15-20 minutes
  • Puy lentils: 25-30 minutes
  • Yellow lentils: 40-45 minutes.

How to purée your lentils

It’s really easy to make a lentil purée. You can either use canned lentils, which will need a quick shower under the tap while sitting in a sieve, or you can use those you’ve cooked yourself on the hob. To whizz them into a thick paste, the general ratio is one cup of lentils to a quarter cup of hot water. Stick it all into a food processor, et voila. Best

Best lentil dishes to try

Lentils are such a versatile food, they’re used in all sorts of dishes, all over the world. They’re a great substitute for meat and can add some much-desired texture to vegan dishes, in the absence of meat or fish. To give you a few ideas, these are a few of our favourite lentil dishes from around the globe.
