This is that honey which Dadhyañc Ātharvaṇa told to the Aśvins. Seeing this, the ṛṣi said: "O men! That formidable deed which you did for your own gain I shall reveal, as thunder reveals the rain: the honey that Dadhyañc Ātharvaṇa told you with the head of a horse."

The madhu-vidyā is clinched with a pedigree — and what a pedigree! Dadhyañc Ātharvaṇa, an ancient ṛṣi, knew the "honey" — and Indra threatened to strike off his head if he gave the teaching away. The Aśvins, the divine physicians, wanting the knowledge, resorted to a stratagem: they took off the ṛṣi's head, set a horse's head in its place, and with that head he told them the honey; Indra struck off the horse's head — and the Aśvins restored his own. The Ṛgvedic verse quoted here (RV 1.116.12) glorifies that "formidable deed".
The legend is no ornament: it is about the price of a teaching. The honey-vidyā cost a head; knowledge of the universal sweetness was handed on under the threat of lightning. There are truths the world (and its authorities) would rather keep under lock — and there are teachers ready to speak them even with a horse's head. Everyone to whom an Upaniṣad has come down drinks honey paid for by someone's courage.
