guava / Durian / Jackfruit
All three in my personal top of the tropical fruits. Durian is the #1 tropical fruit for me, and probably the #1 fruit in general.

I prefer Thai pumpkin - buy it raw (they cut it at markets) and quickly steam-cook it in a rice cooker or in a boiling pan (put a plate on its bottom and add some water to steam-cook your pumpkin). When it's fresh and hot, it's especially yummy. Eating with a tiny bit of butter can make it more filling.
