What to include in a holiday reveal box?

[InTheNameOfAllThatIsHonest]

I am planning to take my OH to Croatia for his 50th next year. I would like to give him a 'reveal box' when I tell him about my plans. What would you recommend I include? So far I have maps and tourist brochures of the region and a phrasebook. I am also looking to try and find some Croatian wine (we are in the UK). But what else can I include? It doesn't need to be expensive, but it should be themed to Croatia. Any ideas gratefully received. Thank you!

The red pepper stuff is Ajvar, available in regular and hot. Do you have local Eastern European/Turkish supermarkets? There are often a lot of Croatian foods available (alongside those of lots of other countries, so if you can't recognise Croatian, that might be an interesting challenge). You can get nice biscuits/cakes.

A recipe for black risotto.

Something to do with Odysseus (he spent a lot of time there (apparently)), or Marco Polo (born on Korcula), or the theory of everything (an idea invented by a Croatian monk).

I will see if we have any nearby! The recipe for black ink risotto had crossed my mind...

Wetsuit shoes, the beaches are lovely but the rocks ripped my bare feet to shreds

We bought some when we went to Hvar - although I think my stepdaughter has them now!
