I save all my "scraps" from the veggies I have used in my cooking. I put
plastic bags in the freezer. When I get two or three large bags of scrap
veggies (or, I'm really bored on a weekend) I throw the frozen masses
into a large covered pot with water with either a cut in half pear or apple
and spices (a bit of pepper, salt, bay leaf, sometimes a bit of basil)
And, boil boil boil. I cook the mess until the whole house smells...usually 1
hour...sometimes more. Then, I drain the 'juice' into another container
removing all the veggie bits and pieces.. and let the liquid cool down.
(make sure to remove the bay leaf.) When, it is cool enough to handle I
ladle the liquid into zip-lock bags and freeze.(I usually divide them up
into 2 cup baggies of liquid). Voila, my freezer is full of veggie broth for
at least a month.
By using Scraps, it doesnt seem like your wasting the entire vegetable to
make broth, right. Plus when your done making the broth the scraps can
still go on the compost pile :-)
