From soil to seed to pan to freezer to pot to pile to soil.
There’s now a “stock bag” in the freezer as a permanent resident. Carrot tops, onion skins, garlic butts, celery ends: they all go in the bag as they depart from their meatier bits that are bound for the pan.
When the bag is full, it goes in a pan to boil and salt, salt and boil, until there’s the most lovely green broth with which to base a soup.
The simmered remnants go to the compost pile, where they transform into soil to feed the future harvest of carrots and onions…
