If you’re one of those monsters who eats salsa straight from the jar? Stop it right now. Double-dipping with a chip introduces bacteria from your mouth into the whole batch.
That can cut the shelf life in half. Use a clean spoon, people. Or at least a chip that doesn’t touch your lips twice. I’m not asking for a miracle—just basic salsa hygiene.
Also, always reseal the lid tightly. Oxygen is the enemy. If air gets in, it oxidizes the salsa and turns it into a science project you didn’t sign up for.
