18th Century Cooking with James Townsend and Son.

What “Portable Soup” Is (Context)

  • Portable soup is a very concentrated, solidified essence of meat, similar to a solid broth/gel.
  • Historically, it was used like soup bouillon.
  • It acts as a flavor booster in soups, sauces, gravies, and similar dishes.

Ingredients (Quantities / Substitutions)

Quantities: The subtitles don’t provide exact ingredient weights—only batch sizing is mentioned.

  • Beef shank (primary meat)

    • Chosen because it’s collagen-rich, which produces good gelatin.
    • Substitution: neck bone is recommended.
    • Other beef cuts can work, but not as well.

  • Water

    • Enough to cover the meat in the slow cooker.

  • Seasoning

    • Typically not added during preparation.
    • Most period recipes suggest adding seasoning when using the portable soup, not while making it.

  • Poultry variation (alternative)

    • Poultry can be boiled in water to form the base.

Equipment + Preparation

  • Slow cooker

    • Medium size; holds about 5 pounds of meat.
    • For larger batches, use a kitchen roaster.

  • Cloth

    • Used for straining/filtering.

  • Cooling setup

    • Period suggestion: woolen flannel cloth
    • Faster home method: cooling rack + fan

  • Dehydrator (optional)

    • Only if it can dry without heating the product back into liquid.

  • Storage wrap

    • Paper (or similar material).

Step-by-Step Method (Timings + Technique Cues)

1) Make the Concentrated Broth Base

  1. Add meat to the slow cooker.
  2. Cover with water.
  3. Seasoning: add nothing at this stage (per subtitles: “most recipes… suggested adding nothing else”).
  4. Set the slow cooker to LOW and cook 8–10 hours.

2) Prepare and Clarify the Broth

  1. Remove the meat.
  2. Pick clean any remaining bones/gristle/fat.
  3. Turn off the slow cooker and let the broth cool completely.
  4. As it cools, fat solidifies on top, making it easy to remove.
  5. Strain and filter the broth through a piece of cloth to remove settled particles.
  6. Rinse out the slow cooker and pour the clarified broth back in.
  7. Turn the slow cooker back to LOW.

3) Reduce to Gelatin (Don’t Burn It)

  1. Leave the lid off.
  2. Cook for 18–24 hours.
    • Goal: reduce the broth to a gelatin.
  3. Key cue:
    • It won’t necessarily become a hard block; it becomes a medium brown, gluey substance.
    • Avoid overcooking—if it gets too hot or overcooks, it can burn and taste very unpleasant.
  4. When gelatin stage is reached, turn off and let it cool completely.

4) Dry Into Portable, Storeable “Leather-Like” Paste

  1. Turn the gelatin out onto a cloth.
  2. Drying requirement:
    • No heat—heat can turn it back into liquid and can burn it.
  3. Drying methods described:
    • Period method: spread on woolen flannel, then flip 2–3 times/day for 10 days to 2 weeks.
    • Faster home method: place on a cooling rack in front of a fan for a couple of days.
    • Dehydrator option: only if it doesn’t heat the product.
  4. End result:
    • A very stiff paste, almost like leather.
  5. Cut into chunks.
  6. Wrap for storage using paper or similar.
  7. It will continue to harden as it ages, but remains usable in its leathery form.

Chef Tips / Common Mistakes to Avoid

  • Don’t let it get too hot during reduction—overheating can ruin it or cause burning, leading to an unpleasant taste.
  • During the drying phase, do not use heat (even moderate heat): it can liquefy and then burn.
  • Don’t expect a final reduction into a hard block—it first becomes a gelatin/gluey substance.

Serving / Use Suggestion

  • Use portable soup like soup bouillon:
    • As a homemade flavor booster in soups, sauces, gravies, etc.
  • It’s also mentioned as the base for their spring soup episode.

Sources / References Mentioned

  • “Bone broth video” (portable soup recipe starts the same way)
  • “Spring soup” episode (portable soup used as the base)
  • A period recipe naming list (portable broth / pocket soup / veal glue / portmanteau potage), but no external written source title is provided in the subtitles.
