This one’s wild. Cold mustard gets uglier. It turns pale and grayish because the turmeric settles out. It looks like something a sick dog left behind.
Warm mustard? It’s vibrant, sunny, and cheerful. It’s the lemonade of condiments. Your sandwich deserves a pretty face.
So, if you’re keeping mustard in the fridge hoping it’ll look fresh, you’re actually doing the opposite. You’re making it sad. Don’t sad your mustard.
