For example Beherovka usually drinks with orange. So you can fill few oranges with syringe Beherovka or Vodka. Tequila with lemon or lime

Than you can eat them on board. It is really tasty

This was old trick for booze into stadiums and college sporing events.
If you try to bring fruits from the ports onboard it will be confiscated for sure. There is more of a problem of health issue onboard cause by fruits and other foods brought abroad than alcohol.
