Astorga has a chocolate museum! It’s well worth the price of 2.50 euros because it has the chocolate samples at the end.
I wish I could bring you back a bar — I got one with almonds that’s both rich and sweet and has an interesting kind of rough texture because it was ground on a rock or something (I didn’t understand all of the Spanish explanation).
Anyway, now I know a lot about the traditional method of making chocolate bars.
