WFMW: Ascorbic Acid to Keep Your Guacamole Green!

Wednesday May 9, 2012

Have you ever made guacamole and not finished it all in one sitting?  In our house, this rarely happens, but when it does — I’m stuck with still delicious guacamole that looks brown and unappetizing the next day.

I recently discovered a secret trick for keeping your guac looking fresh and green — ascorbic acid!

Add a tiny amount of ascorbic acid powder (also known as Vitamin C) to any dish that might turn brown (apples, avocados, etc.) and it will brighten up the color and help prevent the food from browning, or at least significantly slow it down.

Here is a bowl of guacamole I recently made.  Adding ~1/8 – 1/4 tsp ascorbic acid gave it a vibrant green color.

And here is the leftover guacamole 24 hours later.

You can see it is just beginning to take on a brownish hue, but it is way better than it would have been without the ascorbic acid.

More Tips for Keeping Guac Green:

Keep it tightly covered with plastic until ready to serve — this will keep the air out and reduce oxidation.

Keep the pit in the guac — this supposedly helps, but I haven’t had much luck with it.

Add lemon or lime juice to your guac — this works the same way as the ascorbic acid, but you get a much higher concentration of AA if you use the straight powder (and thus, it seems to work longer).

If you usually add lime juice and want to try the ascorbic acid, I would suggest leaving out the lemon/lime juice the first time.  The AA powder will impart a flavor similar to the juice and including both may be more flavor than you want.

Where to find Ascorbic Acid Powder

I had difficulty locating it until I went to a local vitamin shop (I struck out at Whole Foods, Wegmans, Trader Joe’s, and a specialty pharmacy).  I did find it a health food store, but the price was outrageous.

The best price I found locally was at the Vitamin Shoppe.  It was $10 for 8oz, which sounds like a lot, but a little bit will go a long way.

You can also find it online at Amazon and other retailers.

When shopping for ascorbic acid — make sure you get it in powder form with no added ingredients.

    Another use for your leftover Vitamin C crystals: Dissolve some in water and put it in a spray bottle kept in your gym bag. Spray on hair and skin after swimming in a public pool to remove chlorine, protecting blond and colored hair from color changes and leaving your skin chlorine smell-free.
