Theobroma cacao as culinary, purposes. Some mixtures included maize, chili, vanilla ("Vanilla planifolia"), and honey. Archaeological evidence for use of cacao, while relatively sparse, has come from the recovery of whole cacao beans at Uaxactun, Guatemala and from the preservation of wood fragments of the cacao tree at Belize sites including Cuello and Pulltrouser Swamp. In addition, analysis of residues from ceramic vessels has found traces of theobromine and caffeine in early formative vessels from Puerto Escondido, Honduras (1100–900 BC) and in middle formative vessels from Colha, Belize (600–400 BC) using similar techniques to those used to extract chocolate residues from four
Seed tree Seed tree Seed trees are trees left after reproduction cutting to provide seeds for natural regeneration in the seed-tree method. These trees serve as both the gene source for the new crop of regeneration and as a source of timber during future cuttings. Because of its importance, a seed tree should be carefully chosen based upon both economic and biological factors. Selected seed trees should be the desired species, phenotypically superior, prolific in seeding and flowering, sturdy and healthy, free of damage, and of good growth form. After the site has been successfully regenerated, seed trees may be commercially harvested
