Fillings
Buckwheat flour
The buckwheat flour is not a filling: it adds the second batter bowl to your kitchen. From the next day guests can order galettes and, now and then, a sweet crêpe on buckwheat. See batter.
What it opens
Every savoury filling waits for the flour. Until it is bought their cards show a padlock.
Galettes
The flour cannot go back to the market while a filling bought with it is in the shop.
