Mortreux, as expected, was somewhat simpler to make than blank manger but more of a challenge from an edibility standpoint. As it takes its name from the ingredients being mortared, I felt it was incumbent upon me to mortar everything - you can’t take chances with medieval cuisine.
Here’s the recipe again:
Mortrews. Take hennes and pork and seeth hem togyder. Take the lyre of hennes and of the pork and hewe it small, and grinde it al to doust; take brede ygrated and do therto, and temper it with the self broth, and alye it with yolkes of ayren; and cast theron powdour fort. Boile it and do therin powdour of gynger, sugur, safroun and salt, and loke that it be stondying; and flour it with powdour gynger.
What I did was:
Boiled a half chicken with ham hocks (I was unable, after a few tries, to procure pork liver. Who knew?) - because you use a fair amount of the resulting broth in the recipe, I reduced the stock for a while. I then stripped the chicken and the hocks and mortared the meat into a stringy mass.
Cooked about 1/2 pound of chicken livers and mortared them into a fine paste.

In the mortar, I then ground black pepper, galingal (there is some discussion on whether this is the proper medieval galingal - it’s in the ginger family), alkanet (for color, should have used more), nutmeg, and cubeb berries which was my answer to the “strong spice” in the recipe. I added that to the meat and liver and added, bread crumbs, stock, three egg yolks, and saffron. I brought it back to a boil and let it reduce until it seemed like I’d better stop. I powdered it with ginger and let it set. I did not use sugar, though, in retrospect, it probably would have been fine. With so many other flavors in there, it couldn’t have done much harm.
It ended up somewhat reminiscent of pate, though, visually, I have to admit it looked more like cat food.

Served on crusty bread, it had much more flavor than anything I’m used to - not flavor in the spicy sense, but a strange bevy of tastes that co-mingled, overlapped, and attempted to out do each other in the mouth. In this it seemed right - anachronistic, odd, and no doubt perfect if you were working with slightly spoiled meat. Honestly though, it was not bad at all - after you got over the initial shock of it not tasting like anything familiar, you sort of settled in and enjoyed it for what it was. It made a nice sandwich for lunch the next day as well. If you’re trying this at home, shoot for more pepper and less mace and nutmeg - you’ll end up with something that is, while perhaps less authentic, tastier.
The Pye was lovely though:

It contained apples, pears, figs, currants, cubeb berries, cinnamon, cardamom (green), mace, nutmeg. Here the flavors very nearly complemented each other - if you were to dice all the fruits together, and perhaps even cook them together before putting them in the coffin, I think it would be perfect. As it was, one out of every three bites had a lovely melding of flavors, but the rest seemed just slightly disconnected from the ideal Platonic PYE. We used dried figs - fresh figs would no doubt be superior.
Here’s a (slightly out of focus) cross section:
