Your recommendations are really interesting, thank you to you too!, I have been diving in old posts and there are really great discoveries regarding culinary books from all of you, I am delighted. The first recipe I will try then is the Stroganoff you mention, I have an excellent Ximénez-Spínola Pedro Ximenez Sherry that I think it will be perfect for that.
Summer is indeed the perfect time for Okroshkas, Gazpachos, Salmorejos, Ajo blanco, Kheere ka shorbas, etc. I also love acid and all sorts of vinegar, but yours I think is a particular and surely refreshing habit not very widespread. I have a friend who drinks her strong coffee with lemon wedges, that´s also very peculiar.
