I did about half the beans to start and froze them whole in 1qt freezer bags after snapping off the ends. This will be either additions to soups or sides for meals for all of us. The other half I blanched and pureed up for baby food for my munchkin. Even if I over do the quantity on these (I'm sure I'll end up with A LOT of puree!) I can add them to other pureed foods like chicken and potatoes or even pasta sauces and casseroles.
After blanching I added these to my food processor and pureed the heck out of them. Green Beans are stringier and coarser than the squash we blended up in the other post. I still added water in small increments to the beans as they pureed but blended them for about double the time. They are still more coarse but will be palatable for my wee one.
I used a mini muffin pan and a cookie scooper to dole out approximate portions. I stuck this in the freezer for about half an hour then added them to a plastic zippy freezer bag that I labeled with the contents and dated.
Here are the green bean pucks
It helps if you have small helpers snapping the ends off the beans. After they sifted through the discards for bean seeds which we'll try and sprout to grow our own.
