Have You Seen Blue Garlic Color; What Are the Reasons


garlic changes color
We associate garlic with an off-white, uninteresting color. Have you ever noticed a COLOR change in garlic, when it turns to turquoise, blue, or green color, especially when pickled or baked? Why does the garlic change color?



More often that not, most people throw away this type of garlic, fearing health risks. But the color change in garlic is no reason not to use this immensely beneficial herb.






garlic color change
The colors occur as a result of the reaction of enzymes and amino acids with the sulfur compounds present in garlic. So the next time your garlic cloves turn bluish-green, do not be surprised. It's simply the sulfur in garlic reacting in an acidic environment with natural amino acids to form the harmless colored pigments.

The age of the garlic may determine whether it will change color when pickled or cooked or even kept in sunlight.  The garlic is perfectly safe to eat, and will retain the same taste.

So the next time your garlic changes color, do not throw it. Consider using it in the same way as you have been using it for consumption and derive immense benefits of garlic.

Homemade Edible Powders: Beetroot, Onion, Garlic, Ginger, Lemon, Orange, Sambar, Kurma, Garam Masala

The title says it all. This post is all about edible powders that can be used as flavoring agents, natural color, and to make food visually attractive. What more do we need? Though I am not too much in favor of drying food and storing the same, this is the best option for those days when these veggies are out of season. During the season, please make it a point to enjoy these fresh and flavorful. There's nothing better and healthier than fresh produce, right?

Okay so the idea to make these powders popped up in my mind as I had too many beetroots at home. When nobody was too eager to have them, the best way to still consume these beauties was to sundry them to powder. I did exactly that.





Then I wondered if I can sundry lemon peels into powder just like we do to orange peels. I have been using orange peels as a face pack thus far. But since the baking bug has bitten me badly, I plan to use it as an edible powder for cakes and cookies too. Fingers crossed for the results though, sin…

The Best Multigrain Digestives: An Airfryer Recipe

The best multigrain digestives? I know I have shared too many digestives recipes but this one is my best. To be frank, I experiment, relish, share, and post the same for you all and then forget all about it because it's time to experiment again with new ingredients. So today it was another kind of digestives - relished by one and all. My cookie making spree has turned my cookie hater hubby into someone who has started to munch on these baked beauties.



Before sharing the simple cookie recipe, it is time to go through oats benefits. You are already aware of my love for oats. One reason you rarely find my recipes without this fibrous cereal grain. Did you go through the fiber benefits?

Diabetic Diet Cake With Watermelon: A Vegan Recipe

While people are still debating whether watermelon is a diabetes-friendly fruit, I still stick to my notion that diabetics can have this fruit for its sheer hydration effect. Not only this, the fruit is loaded with minerals, nutrients, and antioxidants that make it a health-friendly food. However, diabetics with kidney issues should avoid watermelon. Anyway, let's come back to the watermelon cake recipe for diabetics. Well, this cake uses another fruit - banana- which even I do not think is diabetes-friendly. But I went ahead with including a banana for this recipe merely to keep the fat content low. I hope you all know that a banana is a good substitute for an egg for an eggless cake recipe.

Since an egg is also loaded with saturated fat, diabetics should avoid it at any cost. So I had to choose between an egg and a banana for this diabetes-friendly cake, and ended up voting for this humble fruit - which is one of my favorites too. Yes!

When you think of a vegan diabetes-friendl…
