When I first considered joining a CSA, my biggest fear was wasting too much food.
I wasn't sure I would know what to do with half of the "weird" veggies I received. I was concerned that the volume of vegetables would be more than I could eat. I was afraid I wouldn't commit to chopping, cooking, and otherwise preparing the food I received. I simply didn't know how I would handle all of that perishable produce, and was concerned that it would all rot in the bottom of my 'fridge.
I did a lot of research before I joined my CSA on this very question. And my research all led me to one place.
If you don't know what the heck to do with carrot greens, make broth.
If last week's veggies are still kicking around when you get this week's delivery, make broth.
It's a CSA coping mechanism, and it's a good one.
As it turns out, though, I used most of my veggies in the first week. [Success!]
But I did have plenty of scraps (carrot greens, kale stems, cabbage hearts, etc.) that I collected in a tupperware container in the 'fridge over the course of the week. I threw them all in a stock pot on Sunday evening, filled it with water, brought it to a boil, and then allowed it to simmer on low for 3 hours.
What emerged was a rich, dark broth that is fat-free and salt-free, but nonetheless flavorful and perfect for making soup or cooking grains.
I strained it into a metal bowl and allowed it to cool overnight in the 'fridge before moving it to tupperware containers. I put half in the 'fridge for a soup I have in mind, and froze the other half for later use.
I really love making broth from scraps like this. It must be good karma not to waste a single scrap of plant food, right?
