Molde are starting their Champions League campaign in the second round of qualifying, while the Finnish side have already beaten Larne in Europe this season.
Match preview
HJK began their Champions League qualifying campaign with a 3-2 aggregate victory over the champions of Northern Ireland.
After claiming a narrow 1-0 home victory thanks to Bojan Radulovic's penalty, Larne played out a 2-2 draw in the away leg to set up a tie with Molde.
The task only gets harder for HJK, who have lost their last four ties in the second round of Champions League qualifying since beating FK Ventspils in the 2015-16 season.
The reigning Finnish champions have proven to be a tough team to beat in recent weeks, having lost just one of their last nine games.
HJK will be confident of recording a positive result on Tuesday, with their previous 14 Champions League qualifying home games producing eight wins, four draws and two defeats.
Molde, meanwhile, will head into their first European game of the season in fine form after they extended their unbeaten run to seven competitive games with a comfortable win over Sarpsborg on Saturday.
Eric Kitolano scored the second hat trick of his professional career to put Molde in complete control against Sarpsborg, before Mathias Lovik and Martin Linnes grabbed a goal apiece to round off a 5-0 victory.
Erling Moe's side will now turn their attention to Tuesday's contest where they will be looking to clinch a fifth consecutive victory in all competitions.
The omens are positive for the Norwegian side, who have won all of their previous five ties in the second round of Champions League qualifying.
Molde's only previous UEFA meeting with a Finnish team took place in August 2020 when they thrashed KuPS in a one-legged Champions League qualifying tie.
