Mayo ingredient

EGG

This protein-rich kitchen staple is often cracked open before being whisked into a creamy spread. You might also find it in a carton next to the milk.

The clue "Mayo ingredient" points to "EGG" because eggs are a key component in traditional mayonnaise. Most homemade or classic mayo recipes start with egg yolks, which act as an emulsifier to blend oil and vinegar or lemon juice. There’s no wordplay here—it’s a straightforward definition where the answer is a literal ingredient. If you’ve ever made mayo from scratch, you’d instantly recognize the connection.
