I keep a large ziploc bag in the freezer and any time I have vegetable scraps I clean them and then put them in my veggie ziploc bag.
Examples of veggies that I use for scraps:
- onion rinds and ends
- peels and ends of carrots
- peels of potatoes and sweet potatoes
- garlic ends
- Mushroom stems
- broccoli and swiss chard stems
- ends of celery stalks and leaves
- fresh parsley
You get the point…you can use a lot of different veggies clippings.
When your ziploc bag of scraps is getting full, get out a large stock pot. Put the veggies in the stock pot and cover with water. Bring to a boil then cover on low for 30 minutes.
I use Pyrex containers (the food savers) and only freeze after everything is completely cooled. The other day I made 16 cups of homemade vegetable broth. This is about a $20-$25 savings since this is mostly organic.
Pull the broth out for gravies, stews, soups and more! Wash the bag out and reuse!
