Jambon-Beurre from Stays at IHÉS
Why this dish? Eskin has stayed at IHÉS in Bures-sur-Yvette, France — one of the world's leading mathematics research centers. Between two talks, a quick lunch often takes the form of the most French sandwich of all: a half-baguette buttered with ham, grabbed quickly so as not to break the thread of an idea.
A crusty half-baguette, split, generously buttered and filled with thin slices of cooked ham. Nothing more, nothing less: the French national snack, perfect when your mind is elsewhere, on an open problem.
At Bures, when you're deep into a problem, you don't want to sit down for an hour-long meal — you just want something to keep you going. The jambon-beurre is exactly that: a baguette, good butter, ham, and you head back to the blackboard chewing. I've always felt that France understands something about that — keep it simple, but with real butter and real bread. People underestimate how much a good snack can save the end of a proof.
- •Half-baguette (traditional) — 1 (base)
- •Churned butter — generous (binder and flavor)
- •Cooked ham — 2 slices (filling)

Ingredients
- Half-baguette (traditional) — 1 (base)
- Good-quality semi-salted butter — 20 g (binder and flavor)
- High-quality cooked ham — 2 thin slices (filling)
- Cornichons — optional (tangy touch)
Method
- Split the half-baguette lengthwise without separating completely.
- Spread both inner sides generously with butter — that's what makes it.
- Fold the ham slices inside, without overfilling.
- Close, press lightly, and carry in a paper napkin to the seminar room.
- Eat with one hand, leaving the other free for chalk (optional but traditional).
How it was made : The jambon-beurre is still the best-selling sandwich in France. Born in the 19th century with the democratization of the baguette and Paris ham, it became the universal quick lunch for workers, students — and visiting researchers.
The contemporary twist : Cut it into regular sections and line them up: an edible "tiling" of the baguette, a homage to the billiards and translation surfaces dear to Eskin.
