Dear Barbara: Can you freeze nuts, and for how long? I look forward to your column every week. — Betty
Dear Betty: Yes, you can freeze nuts of all kinds, including pistachios. I don’t freeze nuts when they’re still in their shells, but it is possible. I find them much handier to use if they are already shelled. Freezing nuts that contain a lot of oils, such as pine nuts, will keep them from going rancid.
