Baguette

France — the modern long, thin baguette format emerged in the early 20th century; the 1920 law prohibiting bakers from working before 4am necessitated a bread that could be baked quickly (the thin baguette bakes in 25 minutes vs. 45+ for a large miche); the Vienna-influenced steam injection technique was adopted in French bakeries from the 1840s; the baguette de tradition française regulation was passed in 1993 to protect craft baking from industrial production

France's daily bread — a long (55–65cm), thin (5–6cm diameter), lean wheat bread with a shattering crust, irregular open crumb, and mild tang from a slow, cool fermentation — is the most precisely regulated bread in the world: the 'baguette de tradition française' (defined by French law since 1993) must contain only flour, water, salt, and yeast (no additives, no improvers), must weigh between 250–300g, and must be made and baked in the establishment where it's sold. The crust sound — the crackling sound (le craquage) of a fresh baguette under pressure — is the auditory test for freshness; a mute baguette has lost its moisture balance and is already stale. The baguette's freshness window is precisely 4–6 hours from the oven; after this, the crust softens and the crumb stales irreversibly — which is why Parisian bakeries bake multiple times per day.

Eaten the same morning it is baked — the first meal of the day in France is a baguette from the boulangerie, split and spread with butter and jam, or eaten as part of a tartine with cheese; the crust must shatter and the crumb must have a slight chewiness; with a café au lait (morning) or as the bread for charcuterie and cheese (lunch or dinner); the French relationship to baguette freshness is the most precisely timed in food culture
