I haven't gone over 8 adults yet -- I don't think I have the facilities for more than that for a sit-down dinner. (Perhaps dinner party isn't the right phrase, I basically mean a gathering where dinner is served and good silver is used and there are more than four adults.) Buffet could work for a really biggie though.
Noddy, with a few of these people we do get together more than once a month, sometimes as often as 2 or 3 times a month. The wife in one couple is a Very Good Cook, from Poland, who loads the table with dish upon dish and all of them scrumptious. They keep insisting ordered-in pizza would be fine when they come here but I just can't.
I do ask her for tips but her recipes are extremely complicated and she's been cooking them for 20 years or something. She does repeat, though, which gives me courage to repeat if I hit on something particularly good.
Practice, yes. At home too, without the party, just getting more used to this kind of thing. 10 seems like a lot of meals to me but in the scheme of things I know it's a bare flash in the pan.
I was talking to E.G. about this and he reminded me how much cooking he's done, too, including orchestrating one whole meal that turned out very well. He reassured me that he considers this stuff equally if not more his responsibility since they're "his" friends/ co-workers (though several of them are mutual friends now). He also reassured me that this one uberwife notwithstanding (I do like her a lot though, don't want to hold her culinary prowess against her), there was a party I missed recently where the guy did almost all the cooking, that there isn't a general expectation of the wife being responsible for this stuff. Good.
My amnesia re: E.G.'s participation in meal planning and preparation gave me an idea that I like, starting some sort of cooking journal. What we served, how it went, what turned out well and what could be improved.
But yes, practice, that's the heart of it, I'm sure you're right. If I want to feel natural I just gotta do it more.
Butrflynet. Maybe when our ship comes in. And for the big parties, later on especially (tenure, department chair, whatever), probably. But for these smaller reciprocal gatherings, home-made food feels more appropriate.
Maybe I should start a whole 'nother thread on the faculty spouse business. Sometimes it feels as codified and regimented as being a Geisha...
