Taiwan 2025 - Dried by the Fire

This picture was taken on April 13th and, if one can believe it, the temperature was cool enough to warrant long sleeves for my daily morning hike further up the mountain.  Saw this while passing through the edge of town and stopped for a while to warm up by the fire before continuing.  What are they doing?  Those are thickened tofu skins (made from soy beans) being dried, and presumably smoked as well.  The sign touts the fact that they are "purely handmade".
