I first came across pie, mash & liquor in the wonderful blog Spitalfields Life. This meal is an east London phenomenon, which consists of a meat pie, a pile of mashed potatoes, and a drenching of liquor (parsley sauce). And it seems to be accompanied, traditionally, by jellied eels. (I haven’t come up with a vegetarian version of this, but it would probably involve okra.) The meal is served in gleaming marble and glass pie shops, which I vow to visit one day!
I used a black bean and mushroom substitute for the meat. From the recipes I’ve seen, there’s a bit of leeway with different flavorings – it’s not as pure and simple as a cornish pastie, for instance. I added marmite, mustard powder, paprika, and beer, and the result is really delicious! I have made parsley sauce in the past, but I was in the mood for something different, this time, so I made an herbed walnut sauce, and stirred a big helping of pesto in at the end so it would be green (and tasty!!)
I used a hot water crust on the bottom and a paté brisée on the top, which seems to be traditional, according to some sources. But you could use one or the other. And I used a large-sized muffin pan, but you could use a regular muffin pan, or, to really keep it simple, just use paté brisée and fold them over like turnovers.
