Why do tamales stick after being cooked?

Tamales can stick after being cooked due to a few factors, primarily the moisture content and the type of masa used. If the masa is too wet or not adequately prepared, it can adhere to the corn husks. Additionally, not allowing the tamales to cool slightly before unwrapping can cause them to stick, as the steam can create a bond between the masa and the husk. Proper preparation and cooling can help minimize this issue.
