During the Andalusian summer, the main meal is served at lunchtime, reserving lighter fare for dinner. Everyone comes indoors to take a respite from the scorching sun, and yes, the obligatory siesta comes right after.
I grew up on a farm about an hour outside of Seville, Spain, and entertaining at home was essential; there were no restaurants around us, only roadside taverns, or “ventas,” offering local fare such as snails in tomato sauce. (Not my favorite!)
