You can find Beef Jerky in Flores in the Korean markets, but unless you want some kimchi or Korean BBQ, I wouldn't make the trip there and I would never go at night. My boyfriend is Korean-American and we miss spicy food so we hit up the Korean markets about twice a month. But you can make it in an oven. We used this recipe to make some for a hike in Chile and it worked well with Milanesa meat: http://microwebtech.com/ .
