• Pork fat is naturally white or ivory when cold
• Refrigeration causes it to firm into visible, smooth lumps
• These specks distribute evenly throughout the can (not just on the surface)
• They melt seamlessly when heated, enriching the meat’s juiciness
Key distinction: Mold behaves differently. It appears fuzzy or powdery, clusters on surfaces (not dispersed evenly), and carries sour or musty odors. Fat is smooth, integrated into the meat’s structure, and smells neutral—just salty, savory Spam.
