Lately, I have been obsessed with avocados. However, when buying the avocados, I suck at picking the right one. Every time I buy a ripe avocado, it usually has already turned dark inside. Nonetheless, I have finally mastered a trick to ensure that I get a great fresh and delicious avocado every single time. The trick is to buy them while they're still hard and unripe. Let them sit in your kitchen counter and after a few days your avocados will be ready to eat. Don't wait too long though, or they will have turned. Within two to three days, they will be good and ready to eat. I usually buy around three or four avocados and eat them periodically throughout the week.
