A French luxury item that a war, a wartime flour shortage, and one 1958 shop turned into the city's own sandwich.
As tradition built it
Serves 4. Pre-ferment overnight, dough and bake 3 hours.
Ingredients
- 500 g strong bread flour (high protein)
- 100 g rice flour
- 360 ml water
- 15 g fresh yeast (or 6 g instant yeast) small amount of fresh yeast
- about 100 mg (roughly two thirds of a 150 mg tablet) vitamin C (ascorbic acid), a pinch, as a dough conditioner
- 6 g salt
- to taste pâté, cold cuts or grilled pork, to fill
- to taste butter
- to taste pickled carrot and daikon (đồ chua), coriander, chilli
Method
- The night before, make a pre-ferment (bột cái) from a portion of the flour and water at a 1:1 ratio with a small amount of yeast. Rest overnight at room temperature.
- The next day, combine the pre-ferment with the remaining flour (bread flour and rice flour together), water, salt and a pinch of vitamin C, and mix to a smooth dough at a controlled temperature, around 24°C.
- Prove, shape into batons, and prove again.
- Bake at 220 to 230°C with steam injection, to set a thin, crackling crust before the crumb fully sets, producing the characteristic hollow, crisp shell.
- For the pickle (đồ chua): dissolve 250ml cider vinegar, 200g sugar and 250ml water, cool completely, then pour over julienned carrot and daikon and pickle 3 to 4 hours.
- Split the warm loaf, spread with pâté and butter, fill with cold cuts or grilled pork, add đồ chua, coriander and chilli.
What a modern chef changes
The rice flour taken seriously as bakery science, not folk memory

Method
- Use the genuine poolish-style pre-ferment, not a same-day straight dough, for the faintly sour aromatic depth good bánh mì actually carries.
- Use real ascorbic acid, not a vinegar or lemon-juice substitute: the vitamin C performs a specific oxidative conditioning role a home-cook acid workaround does not, and skipping it produces a drier, less flavourful loaf.
- Bake on a Big Green Egg run very hot with a steam trick (a pan of water or a dedicated steam injection setup), replicating the professional oven's crust-setting steam rather than accepting a denser, less crackling result.
