Is this meant in the sarcastic way that my British mind cannot help but read it...? :)

Maybe they mean when they received fish.

What's the singular, mind or minde?

[Gylej-Gulay]

It is "et minde, mindet, minder, minderne." You can always check any noun and their forms from Ordnet. Here it is for minde:

I also use this site to check for the past or perfect conjugations of verbs; and forms of adjectives. Very helpful!

I really do not understand what this is supposed to mean; in which situation would I say it? To tell somebody what exactly? In German (I am a German speaker) it is not common to thank people for memories.
