@Allexio Well yes you said
("Rare cheese tart"
...
Did you mean "cheesecake"?)
Hence I thought you meant from the picture that it being a mistake? Since she mentions tart but picture shows somthing different. Both does contain cheese just one being cream cheese, the other with both cream and actual cheese, there are also variants from diffrent countries of a cheese tart, know the one from where I live it is not salty but it's because cheddar is not added, its more milky in taste, but guess this depends from where its popular/originated also tart does also require baking to form a crust ontop it on the cream layer.
I can't seem to find the raws on lhscan, so I'm not entirely sure what the raws say compared to the picture, it does seem like a fairly odd representation if the raws are stating "Cheesecake" then.
