For me:
Lidl bakery brownie - not tried, but I think I need to learn my limit
Tiramisu - tried, failed after a few decent table spoonfuls
Smoked salmon - not tried, expensive
Blue cheese - not tried, too scared
DD (26) is the same with salmon and tiramisu, we did the tiramisu together last year. She was making bold claims about coleslaw and sauerkraut, but not sure if there was any action.
