Burger King is running out of Zesty Onion sauce because of a global horseradish shortage.
The fast food company has confirmed the horseradish-based condiment might not be available to some customers, but the team is doing what it can to work on the issue.
A spokesperson said in a statement: ''We are working quickly with our suppliers to maintain continuity and keep offering our guests the zesty experience they love.''
The shortage comes from severe weather hurting Silver Spring Foods' farms and suppliers, and the ability to produce horseradish.
The company is the largest horseradish producer in the world.
