Vegetables that are blue: Are they safe to eat? Find out now!

Okay, so the other day I was thinking about what to cook, and I got this weird idea: are there any blue vegetables? I mean, we got red tomatoes, green peppers, orange carrots… why not blue? So I started digging.

My Blue Vegetable Hunt

First, I googled “blue vegetables.” Seriously, that’s where I started. Most of what I got was about blue potatoes. I’ve seen those before, those purple-ish ones, but are they really blue blue? I wasn’t sure.

• Checked the Fridge: Nope, nothing blue in there, just the usual suspects.
• Asked My Friends: Got some funny looks, a couple of “are you serious?” replies, and one suggestion for blue corn (which is more purple, really).

Then, I went deeper into the internet. I found some articles talking about “blue foods,” and a lot of them were actually talking about fruits like blueberries (duh!) or foods that were dyed blue. Not exactly what I was looking for. I wanted something naturally, shockingly blue.

I even stumbled upon some forums where people were discussing this. It seemed like a lot of folks were as stumped as I was. There were mentions of some obscure mushrooms and some types of corn that can have a blue-ish tint, but nothing solid.

Then I thought about playing with cooking and make some.I remembered that red cabbage can change color depending on the pH of the soil it’s grown in. Maybe I could mess with that? I grabbed a red cabbage from the store, chopped it up, and started experimenting.

• Boiled some: The water turned purple, but the cabbage itself stayed pretty… well, cabbage-colored.
• Added baking soda: Okay, now things got interesting! The water turned more blue-ish, and the cabbage took on a slightly different hue. Still not what I’d call “true blue,” though.

Finally,After all this searching and experimenting, I have to admit… truly blue vegetables are pretty rare. I didn’t find any that were like, bright blue, like a Smurf. But it was a fun little adventure, and I learned a bit about food science along the way. Maybe I’ll try growing some of those blue-ish potatoes next year, just to see what happens!
