The Avengers of avocados - Soft, smooth, and ready for greatness
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I don’t know who’s running quality control over in Haas‑land, but these avocados showed up like they had something to prove. Each arrived at that magical stage of ripeness where you gently press the skin and it gives you that perfect “I’m ready for guac, but I’m also classy enough for toast” softness. The flavor was exactly what you want from a Haas: buttery, rich, and just a little nutty. I cut into each one expecting at least one dud (we’ve all been betrayed by a stringy, brown avocado before), but nope, green perfection all the way through. Honestly, I felt like I should’ve applauded. They held up beautifully in everything I threw at them: sliced on toast, mashed for guacamole, cubed for salads, eaten straight with a spoon like the avocado‑obsessed adult I’ve become. If you’re tired of playing avocado roulette at the grocery store, this pack is a surprisingly reliable win. Delicious, creamy, and ready to be eaten.

Have ordered a few times and they've arrived firm to almost hard and ripen perfectly. Size and quality have been consistent. Honestly, the picker picks better than I do.
