Batata

My mother made a sweet potato casserole that was "Puerto Rican" style. In it the sweet potatoes were yellow and not orange. I never saw an orange sweet potato until college. 

And not a bright yellow that's cheery. Or an autumnal yellow because there is no autumn in Puerto Rico.

No, they were a sad yellow. Yellow after its girlfriend left it for whatever new color Crayola is putting out. Sunshine. And they were stringy. But, the dish still had marshmallow topping. A solid sheet of them forming a puffy top layer in what looked like a yellow and white lasagna. 

Other things that are Puerto Rican style... 

Pumpkin, which is green and small, and only good for seasoning pots of red beans.

Driving. No speed limit on the shoulder and left hand turn on red!

Lettuce, which is wispy and fairy like and would put you to sleep.

Chinese food. It comes with fries.

Crackers. Saltines, specifically. Which in PR come in foil vaccum sealed packs of 6. And they are crisp. You know the Rice Krispie commercials where the kids lose their mind over the noise? But then you eat them and it's mealy mush? Well these crackers SNAP. Sonic boom snap! They come in containers made for astronauts. If not in the foil packs then a giant bongo sized tin of them. They even made whole wheat (Integral) and  "lite" versions

They are a good cracker. Wallace and Gromit approved for sure.
