My Redaction
Stuffed eggs are a widely practiced technique. The period method: hard-cook eggs, halve, scoop yolks, mix with spiced herbs and cheese, refill whites. Scappi's version likely includes cinnamon, pepper, and fresh herbs.
For hospitality service: Make the morning of the event. Needs cooler. Universally appealing finger food. The spicing (cinnamon in the yolk filling) differentiates these from modern deviled eggs and documents the Renaissance Italian palate.
