Please, for the love of guac, do not leave the avocado on the counter after cutting. Room temperature is like a fast track to brown-town. Always refrigerate it—cold slows down the oxidation process.
Also, never store a cut avocado with bananas or apples in the same bowl. I know it sounds random, but those fruits release ethylene gas, which makes your avocado ripen faster—and then rot faster. It’s like putting your avocado in a speeding car with no brakes.
Finally, don’t leave the pit in the water bath. It’s not a magic totem; it’s just a seed that gets slimy. Remove it. Your future avocado half will thank you by not tasting like a wet sock.
