During this period, eggs were a staple in daily diets and held significant symbolic meaning within Jewish culture, representing various aspects of life such as creation, mourning, and celebration.

[1] Hélène Jawhara Piñer notes that during the Spanish Inquisition, traditional Jewish foods such as haminados were used as evidence against New Christians (converted Jews) for secretly adhering to Judaism.

For instance, in 1490, Pedro Martínez from Soria was denounced for consuming red eggs during Lent, a period that coincided with the Jewish holiday of Passover.

Later, in 1505, Alvaro de Luna was tried in Almazán after witnesses reported that he ate red eggs on Fridays and during Lent.

The addition of tea leaves, coffee grinds, or onion skins to the water dyes the shell purple and the white a light brown, giving the egg a smooth creamy texture.
