No, as a rule, recipes aren't copyrightable.

The specific wording and 'flourish' of recipes is copyrightable, but the actual factual, meaningful content - the one which impacts the 'success' of the recipe - fundamentally can't be restricted by copyright, you can't get an exclusive monopoly to make a particular concoction through copyright law (you can with patent law, but it has other restrictions).

It's similar to copyright on design for e.g. clothing - the arbitrary artistic parts can be protected with copyright, but the functional parts can not be restricted that way.

So if you know how to make Coca Cola and want to do that, copyright law won't protect that. Perhaps patent law might (I'm not certain) but there is no patent on the Coca Cola recipe - and if there was, the recipe would have to be published in the patent application, and it would expire in 20 years, unlike copyright. However, you could not freely say that it's exactly like Coca Cola (trademark laws would restrict that), and it does matter how you got that recipe - trade secrets are protected, and if you got the recipe through illegal means (e.g. breaking&entering, or bribing an employee) then you could have repercussions for that.
