Unless you happen to be a squirrel, it's not easy getting these halves and pieces from the hard shell that walnuts grow inside of. But that shell is what keeps them fresh up until they are ready for their debut-and for your snacking pleasure.

Although walnuts often go by the name of English walnuts, their other, lesser-known name-Persian walnuts-is much more apt, as the ancient nuts originated there in around 7,000 B.C. How they landed in California, where the bulk of domestic walnuts are grown today, is quite the adventure tale, with stops along the Silk Road and journeys to far-off lands by caravan and the English merchant marines (hence their more common name). Just think of that rich history the next time you sink your teeth into one of these meaty nuts.

Walnuts also boast a rich nutritional profile and are the only nuts to provide appreciable amounts of omega-3s, making them exceptionally powerful in improving cholesterol levels, reducing inflammation, protecting your heart, and boosting brain power.

These halves and pieces are convenient for baking into wholesome muffins and quick breads, tossing into salads and pasta dishes, using as a crispy coating for chicken or fish, and so much more.
