Nuts can be an expensive purchase, but there are some good buys out there.
Middle Eastern groceries are good places to look. Co-ops tend to have fairly priced nuts, too.
Going to the source is a good idea, for very fresh nuts.
Nuts in the shell will stay fresh a long time; of course you’ll need to shell them to use them.
For pecans, try the Pecan House.
If you have a Trader Joe’s nearby, they have great prices on nuts, especially cashews. Check out their cashew halves and pieces at $3.19/pound, says Ike.
Food clubs, like Costco and Sam’s, sell in large quantities, but it works out to a very good price. Preserve nuts by freezing.
For delicious Turkish pistachios, Zenobia is an excellent online source. They’re not cheap, but the prices include shipping.
