Does mazapan keep? Can I bring it back to the States?

Do you have an airtight container? It should be ok in that case. If you have a box just don't open it, then throw it in your checked luggage for extra frozen powers if it makes you feel safer. Supposedly it can keep (in its original box if its airtight/sealed) for 2 years before going bad.

Ok thanks! It is in the box the woman packaged it in, gift wrapped and everything so I won't open.

Google is a great resource for questions like this. According to what I just read it needs to be airtight. You could stop in at a grocery store and buy Zip-Loc bags, put the marzipan in the bag, suck out the air, then put in another bag and repeat. Marzipan made with egg whites does need to be refrigerated, but some recipes don’t contain egg whites so it depends on how it’s made.

Just saw your 2nd post. If the marzipan in that box is not wrapped airtight it might be a problem.

I've often seen marzipan sold in small cellophane bags on unrefrigerated shelves. I suspect most commercially-prepared marzipan doesn't contain egg whites and will keep for a while. If it was displayed at room temperature in the shop, it should have decent storage qualities. If you purchased it out of a refrigerated case, that would be a different story.

I've enjoyed the marzipan from Santo Tome in Toledo, but I consumed it right after purchase and don't remember whether it was from a refrigerated display. I think some of the products were a combination of marzipan and cookie base, and freshness might be more of an issue there.

Can you go back to the store and ask?

It has 3 ingredients: almond paste, sugar, and egg whites. The sugar is an excellent preservative, but the egg whites are a challenge. I would keep it as cold as possible now, put it in a ziplock bag and squeeze all the air out, and then put it in checked luggage to bring home (it will definitely be cold in the plane’s baggage hold).

@joe No I had already left and was on the train. Doh!

I did write them via email and this was their reply:

El mazapán tiene que conservarse en un sitio fresco y seco evitando la humedad y el calor.

The marzipan must be kept in a cool and dry place avoiding humidity and heat.

that sounds right James.

If you are prohibited from taking them home you could send them to me - I have an idea would could be done with them ;-)
