These biscuits come from the oldest biscuiterie in France, established in Reims in 1756. This features dark chocolate, and is made in the traditional method. The ingredient listing is good, for a cookie, wheat flour, dark chocolate (sugar, cocoa mass, cocoa butter, soy lecithin), sugar, concentrated butter (milk), eggs, dextrose, salt, baking powder and flavour.
How do they taste? The biscuit is crispy, a good biscuit, the dark chocolate is fairly sweet but does work well with the biscuits. I think these are pretty good, not great biscuits. From the box, it looks like they might have some with more interesting ingredients, like rose, but I don't have a source for this kind, nor any other kind. The box of 8 biscuits was $6, so a little pricey.
