Store-bought salsa is a friend who will stay as long as you respect its boundaries. Respect the two-week rule for fresh salsas, stretch to four weeks for cooked ones, and always double-check with your senses. If you’re ever in doubt, remember: when in doubt, throw it out. But also remember that salsa was born from peppers and vinegar—it’s tougher than you think. It’s the Chuck Norris of condiments.
So go ahead, crack open that jar. Just don’t ask it to stick around for a month-long road trip without a little planning. Your tacos will thank you, and your stomach will send you a nice card.
