Many of you are likely to notice how quickly fresh avocadoes (and also apples) get brown, if we try to cook something with them. The reason is that, while cooking them at cold/room temperatures these fruit is sensitive to the excess oxygen (which is more than they can absorb). Lemon can assist to prevent this cooking unpleasantness and keep the colour of your tomorrow’s guacamole as green as it was yesterday. All you have to do is add some lemon juice in this nourishing and sound morsel. The lemon flavor would only make the dish more delicious and healthier.
