The name “liquor” might make you think of spirits, but in London’s East End it means something entirely different: a parsley sauce that has been drizzled over pie and mash for nearly two centuries. The dish is a working-class staple, born in the docklands and still served in traditional shops today. What follows is a look at the history, the recipe, and the linguistic mix-up that keeps people asking what liquor in pie and mash is really made of.

What is liquor in pie and mash made of?

Why this matters

The word “liquor” triggers an alcohol assumption in most readers, but the sauce is entirely non-alcoholic—a fact that home cooks need to know before they skip the ingredient list.

Ingredients of traditional London liquor

  • Liquor is a parsley-based sauce thickened with flour or cornflour (Wikipedia encyclopedia).
  • Traditional recipes use fish stock (often eel), beef stock, or vegetable stock (British Food: A History food blog).
  • No alcohol content in the sauce despite the name (YouTube interview with shop owner).

Why it contains no alcohol

  • The term “liquor” here derives from Latin “liquor” meaning liquid, used historically for any seasoned gravy or broth (Wine Alchemy food blog).
  • In 19th-century London, “liquor” meant a flavoured cooking liquid, not an alcoholic drink (Wikipedia encyclopedia).

The implication: what looks like a cocktail ingredient is actually a simple herb-thickened stock. The confusion is entirely modern—and entirely understandable.

Is pie mash and liquor a London thing?

Cockney working-class origins

  • Pie and mash reportedly originated in the early 1800s alongside the opening of East London docks, serving dock workers an inexpensive warm meal (Wikipedia encyclopedia).
  • The earliest form was eel pie sold from carts and market stalls before minced beef became common (British Food: A History food blog).
  • A documented pie shop was opened by Henry Blanchard on Union Street, Southwark in 1844 (Wine Alchemy food blog).

Spread across the UK and beyond

  • Traditional pie-and-mash shops like Manze, Kelly’s, and G. Kelly still operate in London (Arments Pie and Mash shop blog).
  • Some gastropubs outside London serve updated versions, but the dish remains strongest in its historic East End heartland (Wine Alchemy food blog).

What this means: pie, mash, and liquor is geographically concentrated but culturally iconic. If you want the real thing, London’s old shops are the gold standard.

Eels were originally cheap and abundant in the Thames, but by the mid-19th century the river became too polluted for local eels. Suppliers turned to Dutch and Irish imports, adding cost that helped shift the pie filling to minced beef.

The catch

The shift from eel to beef was driven by rising costs from imported eels, not a change in taste – a practical adaptation that defined the dish’s evolution.

What is the difference between parsley sauce and liquor?

Ingredient differences

  • Parsley sauce is a broader term for cream- or stock-based sauce with parsley; liquor specifically refers to the East End pie-and-mash sauce, often with fish stock (Wikipedia encyclopedia).
  • Some English cookbooks use the terms interchangeably, with liquor as a subset of parsley sauces (British Food: A History food blog).

Cultural naming

  • The word “liquor” preserves an older culinary meaning in London dialect, while “parsley sauce” is the standard modern term outside the East End (Wine Alchemy food blog).
  • In practise, liquor is thinner and more savoury than a creamy parsley sauce, thanks to its fish-stock base (YouTube interview with shop owner).

Why this matters: if a recipe calls for “liquor,” don’t reach for the spirits—reach for a bunch of parsley and a pint of stock. The two names describe one dish, but the historical baggage makes liquor unique.

Why is it called liquor?

Etymology of the term

  • Derived from Latin “liquor” meaning liquid; used historically for cooking liquids (Wikipedia encyclopedia).
  • In 19th-century London, “liquor” meant any seasoned gravy or broth (British Food: A History food blog).
  • Modern usage in East End preserves that older meaning, distinct from alcohol (Wine Alchemy food blog).

Confusion with alcoholic liquor

  • The identical spelling and pronunciation with the word for spirits creates a predictable mix-up for newcomers (YouTube interview with shop owner).
  • This confusion drives many online searches for “what is liquor in pie and mash made of” because searchers assume an alcohol connection (Arments Pie and Mash shop blog).

The pattern: a word that once meant “any liquid” has been narrowed in general English to “alcohol,” but London’s East End kept the old definition alive. The trade-off for preserving tradition is a never-ending FAQ.

How to make liquor to go with pie and mash

The upshot

A home cook can replicate the traditional pie-shop liquor in about 15 minutes with butter, flour, stock, and parsley—no eels required. The result is a thin, savoury sauce that contrasts the richness of minced beef pie.

Step-by-step homemade liquor recipe

  1. Melt 30g butter in a saucepan over medium heat.
  2. Add 30g plain flour and stir to form a roux. Cook for 1 minute.
  3. Gradually whisk in 500ml fish or chicken stock (traditional shops use eel stock; chicken is a modern alternative (Wikipedia encyclopedia)).
  4. Stir in a large handful of finely chopped fresh parsley.
  5. Simmer for 5–10 minutes until the sauce thickens enough to coat the back of a spoon.
  6. Season with salt and white pepper; some recipes add a splash of vinegar for tang (British Food: A History food blog).

Key technique: chopping parsley and simmering

  • Use flat-leaf parsley for better flavour; chop it fine so it blends evenly (YouTube interview with shop owner).
  • Simmer gently—boiling can make the sauce separate or become gluey (Wine Alchemy food blog).
  • The finished liquor should be pale green and pourable, not thick like gravy (Arments Pie and Mash shop blog).
Bottom line: The trade-off: using chicken stock instead of eel stock loses some authenticity but makes the dish accessible to more home cooks. Traditionalists will insist on eel stock; pragmatists will accept the substitute.

What’s unclear

  • Exact etymology of “liquor” in London dialect – speculation but not officially documented.
  • Whether eel stock was always the base or replaced beef stock over time.
  • Precise number of surviving traditional pie-and-mash shops in greater London.
  • The exact location and date of the first pie and mash shop is disputed between 1844 (Union Street) and 1862 (Clerkenwell).
  • The exact percentage of shops that still use eel stock is unknown.

Voices from the pie-and-mash world

“We’ve been making it the same way for 80 years. The liquor comes from the eel stock, parsley, and a bit of flour. No alcohol, just a good honest sauce.”

— Shop owner at a traditional East End pie-and-mash house (YouTube interview)

“Pie and mash is one of the few London dishes that hasn’t been gentrified. It remains a working-class meal.”

— Food historian, British Food: A History blog (British Food: A History food blog)

“The name ‘liquor’ confuses people instantly. I’ve had customers ask if we serve it with a shot. I tell them it’s just parsley sauce—grandma’s recipe.”

— A. Kelly, manager of G. Kelly pie shop (Arments Pie and Mash shop blog)

For anyone searching for an authentic London meal, the message is consistent: pie, mash, and liquor is a dish rooted in practicality, not pretence. The green sauce holds the history, and the name continues to spark curiosity for newcomers seeking authentic Cockney food.

Frequently asked questions

Can Muslims eat food cooked with alcohol?

Yes, because the “liquor” in pie and mash contains no alcohol. It is a parsley-based sauce with zero alcohol content, so it is permissible under halal dietary guidelines.

Is moonshine stronger than regular alcohol?

Moonshine is a distilled spirit that typically has an alcohol by volume (ABV) of 40–60% or higher, but it is unrelated to pie-and-mash liquor. The two share only a word—nothing else.

How much liquor will 5 gallons of mash make?

If you’re referring to the alcoholic mash used in moonshine distilling, 5 gallons of mash produce roughly 1–2 gallons of distilled spirit depending on efficiency. But the question likely mixes up the two uses of “mash” and “liquor.” For pie and mash, one batch of liquor uses about 500ml of stock—far less than 5 gallons.

Is there beef in the pie typically?

Yes, most modern pie-and-mash shops serve minced beef pies. Historically, eel pies were standard, but beef has dominated since the late 19th century.

Do traditional shops still serve eel pies?

A few traditional shops still offer eel pies, but they are less common. Minced beef pie is now the default, though eel pies remain available in shops like Manze and Kelly’s.

Can I freeze pie mash and liquor?

Yes, but it’s best to freeze the components separately: freeze the pie and mash, and make the liquor fresh when reheating. Frozen liquor can separate when thawed.

What is the best potato for mash in this dish?

Floury potatoes like Maris Piper or King Edward produce the fluffiest mash, which absorbs the liquor well. Waxy potatoes yield a denser texture that doesn’t soak up the sauce as effectively.
