I mentioned a couple of weeks ago that I’d frozen a batch of surplus chickpeas after rehydrating them. I can now confirm that they worked perfectly well to knock up another batch of hummus once defrosted.

As a further tip, try spreading them out in a layer in a freezer bag and using a straw to suck the air out (ghetto vacuum pump). This gives an advantageous surface area to volume ratio, which means they don’t take nearly as long to thaw out, especially in a shallow dish of water with a bowl on top to keep them from floating to the top.
