Ah, so you've discovered a typo! Mayo - the sauce, is written with double 'n'! I know. This typeface was called after a Smashing Pumpkins tune that I like extremely much.
Mayonaise is a little an awful duckling. It is odd, open and messy, and may not be love at first sight. BUT, when you spend a long time with Mayonaise and be familiar with her, you may in fact fall in love. Simply like that tune I discussed earlier.
Go on then, provide it a shot! At this rate, you can't go wrong!
