I'm just back from a trip to Hawaii, and hot to make an oven version of kalua-style turkey. Of course, all the recipes call for Ti leaves for wrapping the whole thing up. I don't think I can easily get Ti leaves locally, though I know I can get Banana leaves. I know that you can't just substitute banana leaves because they do have a slight anise flavor--fine if you want it, but definitely not the same.
The problem is I don't know what flavor, if any, ti leaves impart to cooked items. In the case of kalua-style cooking, the leaves are used as a steam-retaining wrap in a low temperature, long cooking situation. Our hosts in Hawaii said they didn't think they have a flavor, but I'm not so sure. There was definitely a slight plant-y flavor to the turkey that I couldn't readily identify.
Does anyone know if Ti leaves have a flavor and what it might be like?
If folks think there's not any (or very little) flavor imparted, what might be a good substitute if I can't get them?
