Hear Business Insider's Katherine Tangalakis-Lippert out: McNuggets and caviar slaps — and it may be just the kind of delightful combination that McDonald's needs right now, she writes. McDonald's launched a pre-Valentine's Day promotion on Tuesday, allowing nugget fans across the country to sign up for free delivery of a 1-oz tin of baerii sturgeon caviar from Paramount Caviar, eight ounces of crème fraîche, and a $25 voucher to buy McNuggets to pair with it, while supplies last. The McNugget Caviar promotion is just the latest in McDonald's recent made-for-a-viral-moment marketing campaigns, and Tangalakis-Lippert writes that she didn't expect to like the combination as much as she did.
