For those who want to know without looking again at the comments: Yes, the cake in the post below was very tasty. I'm not normally a big fan of this sort of cake, but it seemed to be just the right balance between being just moist enough and not too soggy, and having enough fruit to make it flavorful but not so much that the fruit was overwhelming.

Onelia, my hostess, said that the yellow and red waves around the sides were made with colored gelatin. I noticed that the strawberries that ringed the top were dipped in the red gel to really make them stand out.

I'm home from Bolivia and breathing again :-) and will write again in a day or two and tell you more about my visit.
