Chí hǎi was a paste of ant eggs (chí, glossed as "ant young") served at the Zhou court, a historical reconstruction from ritual texts. The Rites of Zhou lists it among the court's hai pastes, and the Han commentator Zheng Xuan describes how hai were made, mixed with millet qu and salt, steeped in good wine and sealed in a jar for a hundred days. No text gives a recipe for the ant-egg paste itself.

Chí hǎi was a paste of ant eggs (chí, glossed as "ant young") served at the Zhou court, a historical reconstruction from ritual texts. The Rites of Zhou lists it among the court's hai pastes, and the Han commentator Zheng Xuan describes how hai were made, mixed with millet qu and salt, steeped in good wine and sealed in a jar for a hundred days. No text gives a recipe for the ant-egg paste itself. Made in 4 steps over 3.3 months. The longest step, seal in a plastered jar until done, takes 3.3 months (Zhouli zhushu (Zheng Xuan commentary).
Chí hǎi is one of the seven hai pastes that Zheng Xuan's note lists for the king's meals, and the only insect among them; the others are made from meat juice, snails, clams, fish, hare and goose.
No Zhou text says how safe the paste was. As a general hazard for insect foods, a 2026 review in Foods reports Bacillus cereus in dried and powdered insects sold in Europe and Asia, and says wild-harvested insects from contaminated places can carry more pesticide residue than farmed ones. This is not a finding about chí hǎi.
The Rites of Zhou (Zhouli), office of the hairen (醢人), lists chí hǎi among the dou dishes of offerings, and Zheng Xuan's note on the seven hai for the king's table includes it. The turtle officer supplies ant eggs to the hai office for sacrifices. The Book of Rites (Liji), chapter Neize, pairs dried spiced meat with chí hǎi. Zheng Xuan glosses chí as 蛾子, "ant young", after the Erya dictionary.
