From cook's illustrated magazine. Make your own vegatable broth base, ready to use anytime straight from the freezer. I am intrigued by this recipe and hope to make it soon.

Steps

---

Process everything , except tomato paste and soy sauce , in food processor , scraping down sides of bowl frequently , until paste is as fine as possible , about 3 to 4 minutes.

---

Add tomato paste and process for one minute , scraping down sides of bowl every 20 seconds.

---

Add soy sauce and continue to process one minute longer.

---

Transfer mixture to airtight container and tap firmly on counter to remove any air bubbles.

---

Press small piece of parchment paper against surface of mixture and cover.

---

Freeze up to 6 months.

---

Use 1 tbl to one cup boiling water to make broth.

---

Strain if you desire a particle-free broth.

---

The salt content of the mixture will keep it from freezing so that you can scoop it straight from the container.
