There wasn't a wide choice of refreshing drinks in my childhood. That time in Hungary we could choose only three or four drinks, for example between Traubi and raspberry syrup. My grandmother used to prepare raspberry syrup every year and we drunk it with soda (sparkling water). Her version was very delicious and natural.
Nowadays the raspberry syrup is living its Renaissance. It's called "málnaszörp" in Hungarian and you can find it in any of the Hungarian supermarket or you can order it in some retro place. Don't forget to try it one day!
