Is it youghurt, yoghurt, or yogurt?
Is there a correct spelling, or are they all correct?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
OED to the rescue:
'Yogurt' is the commonest, followed by 'yoghurt', probably because they are easiest to remember/repeat. But early adopters (and modern posers) tried any transliteration of the Turkish.
