Perfect Guacamole: Vacuum Seal to Preserve

There is no better way to actually prevent your delicious guacamole from browning than vacuum packing!

An enzyme (polyphenol oxidase) in avocados causes the flesh to oxidize when exposed to air, turning it that dreaded brown color. That’s why an avocado is often green underneath the pit but browned on the exposed surfaces surrounding it — the surface underneath the pit is protected from oxygen, so take away the air and vacuum seal it.

• 1 serrano chile(s), or similar, or more to taste
