I'd like to say
I'm baking a cake à la Ramsey.
Here, à la means in the style of. My problem is: what if Ramsey is male? The French la goes with feminine nouns. So, should I write the following?
I'm baking a cake au Ramsey.
That might be more grammatically correct in French, but seems wrong in English, since au isn't a phrase in English in the same way that à la is.
