Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pork Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the pork
Remove the rind and part of the under bone from the loin of pork and cut it into chops.
Season the chops with pepper and coarse sea salt.
Make the pastry
For the puff pastry, mix together ½ pound of sifted flour, 6 ounces of fresh butter, and the yolks and whites of 2 eggs.
Assemble and bake
Cover the seasoned chops with puff pastry and bake at 400°F (200°C).
When serving, pour cullis mixed with the essence of two onions and a little mustard into the pie.

- Puff pastry
- Forms a crisp, flaky crust that encloses the seasoned chops while baking.
- Eggs
- Add structure and richness to the pastry dough and help it bind.
- Fresh butter
- Adds fat that creates flaky layers and rich flavour in the pastry.
