Andorra’s snack map is Catalan mountain food plus a customs loophole. Carquinyolis from a village oven are the thing that actually tastes like here: almond, egg, a rusk you cannot eat politely. Trucha de Nadal shows up in December, filled with cabell d’angel, and has nothing to do with fish despite the name.
Tourists load shopping bags with Toblerone and turron because the principality prices chocolate like a sport. That is real. It is also not the same as a local sweet. If you only have an afternoon in Andorra la Vella, buy the rusks and a jar of mountain honey, then steal a Spanish bar at the checkout if you must.
