What the traditional version is
A thick centre-cut beef joint seared heavily in a hot pan. Finely chopped chestnut mushrooms are cooked down in a massive chunk of unsalted butter to make a rich duxelles. The cooled beef is coated in a thick chicken liver pate, wrapped tightly in slices of prosciutto, and finally encased in raw puff pastry before being baked to a deep golden brown.
What changed, and what each change costs
Swapping the heavy liver pate for 30g of Dijon mustard
Chicken liver pate is traditionally half butter by weight. It adds a gamey richness, but it also turns into liquid fat in the oven and destroys the pastry from the inside out. I brush the meat with a sharp mustard instead.
What it costs you. You lose that earthy, metallic depth from the liver. The mustard gives a sharp tang, which cuts through the pastry beautifully, but it completely drops the traditional rich flavour profile.
Dropping 50g of butter from the mushroom duxelles
Mushrooms are absolute sponges. If you put 50g of butter in the frying pan, they just drink it and release it back into your pastry while baking. Dry-frying them draws out the moisture so they actually protect the crust.
What it costs you. The mushroom paste is less rich and silky. It acts more like an intense, savoury moisture barrier than a decadent sauce in its own right.

The method is in the book
This is the first and only time I will tell you to skip pate on purpose. Because there's no layer of melting fat trapped inside the parcel, the pastry stays brilliantly crisp on the bottom. So: a structural triumph. A dry imitation was never on the table once the fat came out. The mustard cuts through the richness of the dough, and the dry mushrooms pack a massive savoury punch. Serve it with steamed greens and a strong, hot gravy.
