Our ranchito in Michoacán, México gets quite a few vendor vehicles serving the area with bread, tortillas, fruits and vegetables, cleaning supplies, and groceries in general. They usually have taped spiels (Sometimes intelligible, more often not) accompanied by music. It's very charmingly old fashioned.
Just now was a first for me. I heard the music and announcement of a loudspeaker. I went out to see what it was. Our landlady, Sra. Chucha, was buying menudo de becerro (Calve's tripes in chile broth) from another woman who had it in a large pot in the trunk of her car. The customers bring their own containers. The actual tripe pieces, rather gray and unattractive, sat off to the side in a large bowl. I don't know what it cost, as it didn't ignite my appetite. I didn't particularly like the smell, either. But it was the first time I'd seen Menudo Free Delivery out here in el campo.
My previous posts on "Confronting Menudo" are here.
(Today's menudo wasn't as attractive as that in the photo above.)
