For veggies like beans, chard, corn, and broccoli, blanching and freezing is a great way to store produce. It's a pretty simple process of plunging cut veggies into boiling water, then into ice water to cool. This website has a good run-down of blanching times for different vegetables. Caveat: one guideline that we choose to ignore is that you should blanch summer squash. We just shred it and freeze it without cooking it. I know you're not supposed to, but we actually find that the quality and texture is much better when we do use it (we cook it in fritters and muffins and such), and have never had a problem with it going into the freezer raw. Still, everyone should make their own decision about that!
The final haul! With lots more to come in the next few weeks. This is the first year we've blanched and frozen peas, since it is the first year we've grown shelling peas. We'll do a taste test in the next couple days on the blanched ones and see how they worked out.
