My boyfriend, Richard, is an eagle scout which is the highest rank a boy scout can achieve. Only 10% of all boy scouts ever make it this far. Richard told me how they used to make silver turtles at their camp outs and that they are best when cooked over coals flipping them every 15 min until done, or bury them under the coals for 30-45 min. I finally got to try these but they were prepared on the grill. I think the oven will be ok as a last resort as well.
