Hi, Gil.
Best of luck with this new project. I am not much of a cook. My skills are limited to survival cousine :)
But I used to eat a lot, almost anything. I lived in the states for some time and I enjoyed going to different counties to try foods from different cultures.
At the moments, given the horrendous crisis we've been going through in the last decade, our diet has been limited to very basic items.
About your questions

1. What weird flavors of food combination do you really enjoy?
   I like black beans with sugar, which many of my fellow venezuelans would rather eat salty or tasteless.
2. What's the worst food you have eaten?
   Hard to tell. can't recall. I have tried some afican food, like chicken with peanuts that i did not like that much, but nothing as bad that would make me throw up or something.
3. What's in your fridge right now?
   some fish
4. What's your favorite food?
   can't say one in particular. I love most foods. From paella to roast meat, from (chicken, fish, meat) soups to pasticho. I love sea food in general and I die for any dessert, especially icecream and cakes.
