Have been invited to an Easter Sunday lunch (well, it starts at 2pm, so whatever the heck you'd call it) and have been charged with organising the wine (shame I can't charge her back for however much it'll cost! Think someone else is handling the dessert wine though.)
Trying to think what in the world would pair well with tzatziki. 1) Because I haven't had it before and 2) because the vast majority of wines would cover up whatever flavour a cucumber has.
Have read suggestions to pair it with pinot noir, gewürztraminer, or sauvignon blanc, all of which seem far too heavy to me :o I was thinking more in the realm of zero-dosage champagne (not that I'm actually going to stretch for champagne) to match the delicate flavour that I imagine tzatziki has.
Or dry prosecco/Clairette de Die.
The main course is slow cooked lamb, which will probably go nicely with a Rhône wine. I wonder if something from Languedoc would be too "unserious". South West would certainly be too tannic for their palates, though in my experience roast meats and Madiran are…something to have again…
