pecan

This term refers to both the biological organism and the food product derived from it. When referring to the tree, it is treated as a standard countable noun. When referring to the nut as a food ingredient or bulk substance, it often functions as an uncountable mass noun, though individual nuts are still countable. In North American English, the word is frequently associated with regional culinary traditions of the Southern United States, carrying a connotation of warmth, home-style baking, and autumn harvests.
