Halakhah for Chullin 215:5

To not eat meat with milk: To not eat meat with milk that has been cooked together, as it is stated (Exodus 34:26), "you shall not cook a kid in its mother’s milk." And this verse comes to forbid eating and deriving benefit (pleasure) from the meat with milk. And let it not be difficult to you - [that] if so, why is its prohibition not stated explicitly, as "you shall not eat," and [instead] expressed with an expression of cooking. As the answer to this [is] because there is a novelty in the prohibition of its eating above the eating of the other prohibitions. As with other prohibitions, the liability is only if he enjoys his eating. But here even if he does not enjoy his eating, once he swallows it - and even if he swallows it hot and he burns his throat with it, and similar to it - he is lashed nonetheless. [It is] as they, may their memory be blessed, said in Pesachim 25a, "For this reason did [the Torah] not write, 'eating' in [the verse] itself: To say that one is lashed [even when consumed] not in the way of its enjoyment." And nonetheless, we do not administer lashes for it unless it is by way of cooking (Chullin 108a), according to the language that the verse expressed its prohibition.
