Yesterday was a great day. I've had this bamboo-cooking experiment on my list of things to do to prep for the donor group from the American Birds Conservancy. Adrian said that he learned this technique in Indonesia and thought that it might make for a memorable experience for our guests. Of course it sounds really easy: cut a section of bamboo, shove some food in it and stick it in the fire. As with many things in life, very simple concept, takes a bit of planning to execute well.
Determined to test this cooking method, I had Juan cut me a few sections of bamboo while I was up on Cerro Osa yesterday morning. This is when we started to flesh out the details. When I first told Juan that we were going to cook in bamboo, he told me we couldn't.
"Why not?" I ventured. I knew that there was a high likelihood that the food wouldn't turn out, but I couldn't understand his adamant response to my request for 3 sections of bamboo.
"Se va a reventar!" It will explode, he said. Aha, our first obstacle. Something had been lost in translation.
If you look at a section of bamboo, it is sealed on both ends. OR, depending on how you cut it, it could be open on both ends. OR, if you are adventurous, you can leave one end intact while making your cut to open the top of that section. Juan had obviously been thinking no further than option one, closed on both ends. And I would have to agree with him that if you threw that into a fire and applied some laws on the behavior of gases that you learned in middle school, I wouldn't bet against that thing exploding. It made me wonder if he had thought about how we would get the food inside if both ends were closed.
After I explained to him that essentially we wanted to make bamboo pots, closed on the bottom, open on the top, we were in business. Or were we? There are about a hundred different plants to choose from just in one bunch of bamboo depending on how green you are looking for, overall diameter, and thickness of the wood. We went back and forth, Juan arguing for a drier piece, with me countering that we were going to put this in a fire after all. Again, thinking about what fire does to dry trees [even though bamboo is technically a grass], I won the argument and we ended up with these:

This gives you a pretty good idea of the concept. I rinsed the insides out a little bit and then let them soak for a couple of hours with boiled water before we filled them with food. We put chopped vegetables in one, rice and vegetables in the second and chicken and rice in the third. Traditionally you are supposed to close the top by packing banana leaves in, allowing the food to steam and cook faster. You also would supposedly only cook like this if you're stranded somewhere and using this as some sort of survival technique ... or you're crazy.
Since we weren't stranded, we chose to not use river water and banana leaves, and opted for water out of the tap at the OBC [which is connected to a tube that takes the water directly from the river] and aluminum foil. With everything ready, Cheryl, Wibke and I headed down the Rio Piro trail to the beach where I had already collected firewood to get dinner started.
We waited until there were red hot glowing coals in the bottom of the fire before placing the bamboo in the flames. Then there was nothing to do but wait. After about 15 minutes we checked and were extremely disappointed to find that the water wasn't boiling yet. We sampled some of the food and found that is wasn't even warm yet. Really? These things had been sitting on hot coals for 15 minutes and the insides weren't even warm. Not to be dissuaded, we grabbed more wood and stoked the fire until it was raging around the bamboo pots - at this point we had nothing to lose. This time we waited about 30 minutes before checking again and were happy to see that it seemed to be working.
Here's the trick. After more than an hour, and a lot of firewood from the beach, we had succeeded in getting the insides boiling and well on the way to a delicious meal. What we learned was that the bamboo actually has to start burning from the outside in to cook completely. At least that was true for the thickness that we were working with. I'm sure it would be different with thinner sides.
The pots couldn't be removed from the fire until the flames died down, and only then with the help of some branches; remember that these pots themselves now were essentially on fire, glowing embers surrounding the food inside. We took them out, one by one, and set them in the cool sand away from the fire. With much anticipation, I took the first bite. Delicious!
I can't say that the rice and chicken had a "bambooy" flavor as much as a char-grilled smokiness about it. But I can say that we had success with a first attempt and that we'll only get better with this interesting and special way of making a meal.
You may scoff and ask why you would do this when you can just cook like "normal." I would answer that everything takes longer here and that's what is so special about this place.
