We ate a lot of fabulous food but my sister and I are also stuck on the olives. She only had 5 left when I spoke to her the other day.

Wow! Didn't see this until now and I was waiting for it.
As usual you had a wonderful trip and great food. Someone today was asking about Barcelona so nice I can top this for her.

"Abuela" is a word for "grandmother" in Spanish. So it is possible that if you asked at the olive bar what kind of olives you were eating you were told that they were "grandma's" -- meaning a family recipe, not a commercial brand.
