Here's a real quicky tip because it's Friday, and I know you're busy and trying to get things done before the weekend, and I'm busy, and really distracted thinking about bananas. Wait, what? You heard me- bananas, people. You know how, no matter what you do, you always seem to end up with one or two overly-ripe bananas at the end of the bunch? It's not really such a bad thing, because it gives you an excuse to make delicious banana bread (you can also freeze them for making smoothies later on), but it's kind of annoying how fast those nanners ripen, right under your nose. So here's a tip for delaying the speed at which those suckers turn brown and narsty: Separate them. You don't have to, like, put each banana in an opposite corner of the room, just keep them from being so snuggled together. Each banana gives off ethylene gas and enzymes which cause all the other ones to get riper faster. If you break all the bananas apart at the stem when you get them home, you will delay the ripening process.
So, you want your bananas to stay just right for longer? You gotta keep 'em separated.
