banana bread

this was only my second attempt at baking banana bread. i've never considered myself a baker of sorts, and don't usually have the inkling to mix up dough and utilize my oven. but, there are those accasions when the bananas in the basket have crept just past their ripe status and into the relm of black and icky. at our house we go through fruits and veggies like monkeys, so this is rarely a problem. the first time i made banana bread was a couple months ago, and it was dense and dry. chad told me it was delicious-bless his heart- but i know the truth. it was like eating sugared cotton balls. this time, though, was much better. i added an extra banana for more moisture and it turned out beautifully! delicious!

why do the banana chunks turn purple?
