Nuts: Common

12 questions · Nature

Nuts sit in every Christmas bowl, hide in chocolate, muesli and pesto: but who can reliably identify them once they are out of the packet? This pack brings together the twelve best-known kinds and makes you familiar with them straight from the photo. You will meet the walnut with its furrowed shell, the hazelnut in its leafy cup, and the almond, which botanically is not a nut at all but the kernel of a stone fruit. Then there is the peanut, in truth a legume that ripens underground, the kidney-shaped cashew, the green pistachio, the angular Brazil nut, the round macadamia and the elongated pecan. Sweet chestnut, coconut and pine nut complete the round. What makes it interesting is that many of them are not true nuts in botanical terms at all; the everyday word is far more generous than botany. Did you know that the macadamia was long considered the most expensive nut in the world? Its shell is so hard that it withstands pressure of several hundred kilograms and has to be cracked by machine.

Cashew

The kidney-shaped cashew grows on the outside of a fleshy ‘cashew apple’. Its shell contains irritants, so it is never sold truly raw.

💡 Did you know? ‘Raw’ cashews in shops have still been gently heated.
