I made my own vegetable broth today. I had been saving vegetable scraps in the freezer till I had a large freezer bag full.
I simmered them along with various herbs and spices (already forgot what they were) in water for a couple hours occasionally mashing them with a potato masher.
I then strained it through this wire basket thing. It made more than I had containers to store it so I drank some and through the rest out.
