Let’s break it down, because you’re a savvy shopper (or a passionate home cook). Homemade pesto is glorious, but it’s also fragile. Fresh garlic, basil, and cheese are a party for your taste buds, but also a party for bacteria. That’s why it only lasts about a week.
Store-bought pesto, however, is a little cyborg. It’s been pasteurized, pumped with preservatives, and sealed tighter than a clam. That’s why it can drift along for up to 14 days in the fridge. But seriously—if it’s been two weeks and there’s a weird fuzzy hat on top, throw it away. No prize for bravery.
How to Tell If Your Pesto Has Gone Rogue
You don’t need a lab coat to spot bad pesto. Look for three things: color, smell, and texture. If it’s turning brownish-gray or developing dark spots, it’s past its prime. If it smells sour, funky, or like old cheese that’s plotting revenge, definitely toss it.
How Long Does Pesto Last In The Fridge After Opening?
And here’s the big one: mold. Fuzzy spots are a hard no. You can’t just scrape them off and pretend they’re fancy seasoning. That’s not how the pesto game works, my friend. One bite of bad pesto and you’ll be best friends with your toilet for the night. No thanks.
