Le Jambon-Beurre "Fait Maison"
Le Parisien·(zhahm-bohn-burr)
Chapter 4 — The Cheese & Bread Course
There is a specific moment at 11:45 AM in SoHo when the morning pastry rush fades and the pewter bar is wiped down for lunch service. The air smells of espresso, faint anise, and the sharp tang of sourdough. This is the habitat of the iconic jambon-beurre. It is a sandwich with nowhere to hide: just bread, butter, and ham. You cannot fake it with a soft sub roll or water-pumped deli meat. You need a shatteringly crisp ficelle, unsmoked wet-cured Jambon de Paris, and an aggressively tangy, 83-percent-fat cultured butter you are going to churn yourself. When you finally bite into it, it fights back, and you will know exactly what Spring Street tastes like.
Before you start
Start the butter a day ahead
The cream needs 12 to 24 hours of room-temperature fermentation before it is ready to be churned.
Ferment the dough overnight
The lean bread dough requires a 12 to 18 hour cold retard in the refrigerator to develop its complex blistered crust.
Ingredients
- heavy cream1 qt
- cultured buttermilk2 tbsp
- fleur de sel1 tsp
- ice water4 cup
- bread flour500 g
- water375 ml
- fine sea salt10 g
- instant yeast3 g
- Jambon de Paris12 oz
- Cave-Aged Gruyère4 oz
- cornichons8 med
Method
- 01
Culture the cream
In a large glass jar, whisk the heavy cream and buttermilk together, cover loosely, and leave at room temperature for 12 to 24 hours until it thickens like crème fraîche and smells distinctly sour, then chill it for at least two hours.
- 02
Churn the butter
Pour the chilled cultured cream into a stand mixer fitted with the whisk attachment, drape a towel over the machine to catch the inevitable splatter, and whip on medium-high until the fat solids separate entirely from the buttermilk.
- 03
Wash the butter completely
This is non-negotiable; if you do not wash away the remaining milk proteins, the butter will sour and spoil rapidly. Pour off the buttermilk, add ice water to the bowl, and knead the butter with a wooden spoon to squeeze out the cloudy liquid, repeating with fresh ice water until it runs crystal clear before folding in the fleur de sel.
- 04
Mix and hydrate the dough
Whisk the warm water and yeast in a large bowl, add the bread flour to form a shaggy mass, and let it rest for 20 minutes to autolyse before pinching in the fine sea salt.
- 05
Build structure and cold ferment
Perform a series of stretch-and-folds every 30 minutes for the first hour and a half, then cover the bowl tightly and banish it to the refrigerator for 12 to 18 hours to develop that essential brasserie tang.
- 06
Shape the demi-ficelles
Turn the cold dough onto a floured surface, divide it into four equal pieces, and gently roll each into a tight 12-inch cylinder before proofing on parchment paper for one hour at room temperature.
- 07
Bake with aggressive steam
Score the loaves with three diagonal slashes and slide them onto a 475°F preheated pizza stone. Immediately pour boiling water into a cast iron skillet waiting on the bottom rack and shut the door quickly, baking for 12 minutes with steam, then 10 to 12 minutes without, until shatteringly crisp and deeply browned.
- 08
Assemble the sandwich with conviction
Slice the cooled ficelles lengthwise and spread an unapologetic, tooth-mark-thick layer of your cultured butter on both cut sides. Gently fold the delicate Jambon de Paris to create volume and air pockets, then layer it with the Gruyère and cornichons.
Notes
Source true Jambon de Paris
Do not use smoked or honey-baked deli meat; seek out wet-cured, unsmoked Parisian white ham for the proper delicate flavor contrast.
The purist's homemade ham
If you insist on total authenticity, you can wet-cure your own trimmed pork shoulder in a 10-percent salt and juniper brine for 48 hours, then poach it tightly wrapped in a torchon at exactly 154°F.
