Shelf-Life of Walnuts

Walnuts are a reservoir of high-density lipoproteins (HDL), these are heart-healthy fats. Walnuts contain a large number of antioxidants that help to improve a person’s health and are beneficial for anti-aging and can help improve brain health and function. Research has also proven that if eaten in small amounts on a regular basis, walnuts can prevent heart disease and cancer. Walnuts can be easily stored in the pantry for up to 6 months. If stored in the refrigerator, walnuts can easily last for over a year.

Purchasing Walnuts

The first thing that you want to keep in mind while purchasing walnuts is that your nose always knows. Old and rancid walnuts usually smell bad and should be your first clue. It is usually best to know the supplier; the USA exports the largest quantity of walnuts around the world. If buying shelled walnuts, make sure to inspect the shell for any cracks or openings, because a cracked shell can mean that mold has already made its way inside the nut. The amount of space inside the shell matters. The greater the rattling of the walnut within the shell, the easier it is to crack. And of course, since everyone knows, appearances matter, walnuts are no different. Avoid buying walnuts that have an especially dark or have a rubbery shell because this could mean that the walnut is old and past its ‘best by’ date.

Storing Walnuts

It is best not to shell the walnuts for as long as you can. Shelling them just before eating them can mean that you get the freshest taste. If using walnuts straight out of the refrigerator or freezer, they thaw quickly at room temperature. Walnuts that have had their shells removed need to be stored in a refrigerator or freezer and in an airtight container for the longest possible shelf life. Shelled walnuts can last in the refrigerator for about 6 months and in the freezer for over a year. Walnuts with shells and walnut oil can be stored for up to 3 months in a cool dark place.

Handling Walnuts

Roasted walnuts are a globally preferred way of consumption of this delicious nut. People love to roast and cook them and add them to their cereal and milk. Walnuts should always be washed before they are shelled and then dried afterward. Use a nutcracker to remove your walnuts from their shells.

Cooking Walnuts

Walnuts help accessorize the most amazing dishes. They can be roasted for the conservation of their own unique flavor or eaten raw. When toasting, to ensure that all walnuts cook evenly, spread them out before placing them in the oven. Remove only after they have a golden-ish brown hue. Honey-glazed walnuts can be the most delicious and nutty treat. If not, mixing a couple of chopped walnuts with cinnamon and honey can create a unique dish in very little time. Candied walnuts are a walnut specialty; they can be made by caramelizing walnuts and then left to solidify. This creates a unique crunch, and the sweet caramel compliments the flavor of the walnut.
