I just found a product that I have fell in love with. Lime Salt! I love avocados but I only eat half at a time. In the past, I would save the other half in a bowl and put a fair amount of lemon juice on it and toss, put plastic wrap both loosely and tightly against the avocado as well as with the pit and without. Each and everytime, the next day, it would look disgusting. I'm sure it was fine to eat but I just couldn't do it. I found the lime salt in the Mexican section of my local grocery store and it sounded good and got it home and couldn't think of anything to use it with. The first thing I tried it on was a batch of margarita mini cupcakes. I frosted the cupcakes with a lime buttercream frosting and then a slight pinch of the lime salt. It was great, and really made a huge difference in the taste. Then about a week after the cupcakes, I decided to have a salad with avocado and only used half of it. I cut up the avocado to use later and tossed it in about 1/8 tsp. of the lime salt. Well, the next day I didn't eat the avocado. Two day old avocado in the refrigerator, still looked and tasted great. So, I decided to take my little experiment further and retain some of the avocado for another day. Three day old avocado was just starting to turn, it wasn't quite as green as day 1, but it was not brown nor blotchy. That was as far as I took the experiment. Finally, a successful attempt to save avocado for another day.
