Apple Caviar – Humble Beginnings in Molecular Gastronomy

If you are one of my friends in facebook, you should have noticed that I kept on asking around on how to get my hands on sodium alginate! Luckily, one of my friends knows a company that process seaweeds derivatives and thus, able to make this post! Yay! Lemme show you my first step in molecular gastronomy 😀

Chefs like Ferran Adria of El Bulli, Heston Blumenthal of The Fat Duck Wylie Dufresne of WD-50 use this discipline in their craft. It gives you an idea how food can be more surprising than you could have ever imagined! It was actually Ferran Adria who pioneered of using molecular gastronomy to the next level! If I am not mistaken, this cooking is all about perception. Change of perception on the food surprises people and it gives a whole new dimension on the dish that is being served! 🙂

Anyhow, let’s start doing some food chemistry now! 😀 For me, I think one of the basics of molecular gastronomy is food spherification. Food spherification is technically turning some sort of liquid into a sphere by the use of two main ingredients: calcium chloride and sodium alginate.

One needs proper precision so that execution is spot on! 🙂

First make a calcium chloride solution! 🙂

As the post says it, we will use apple juice with the alginate 😀 I made some apple juice and strained them since you just want pure liquid! 😀

To incorporate the alginate, you need to put the juice in a blender. 😀

You have to do this because you can only incorporate the alginate evenly while the blender is on with the juice! 🙂

When that is done, put the alginate/apple juice solution inside a squeeze bottle! 🙂

Then, squeeze out the juice one by one into the calcium chloride solution! 😀

Tada! 😀

Here is the tricky part, the calcium chloride solution gelatinizes the alginate solution. The longer it stays in the calcium chloride solution, the thicker it becomes. We want it to ‘pop’ like caviar. We just need a thin coating of gel. With that in mind, after placing the alginate solution, you have to scoop it out and give it a water bath to stop the gelatinizing process! 😀

Then plate it hohoho! This is, so far, my favorite dish 🙂

    very good job! haha its cool na u got the spheres spherical in shape tlga haha i think ferran nappes more apple essence on to the finished apple spheres para itll be more intense and caviar like yung experience. 🙂


    • Yep, and the caviar like experience is all about the timing and the size of the syringe, I used a squeeze bottle so the surface area is smaller thus it doesn’t pop up that quickly 😀

    make other colorful stuff too! that would be nice! ❤


    • I shall do it 😀 but it this stuff is tricky, not everything can be sphered perfectly due to some chemical reactions of the ingredient itself 😀 I made something like this before but it didn’t turn out good since the ingredients were already too complicated so I resulted to something pretty basic, then I will gradually make it more sophisticated 🙂

    Great job! masubukan nga.. hahaha! where did you get you sodium alginate? alysons dn? kailan pasukan nyo pla?


  6. Texture is more important to me than it is for most people, so this is very interesting! Yes, please, sana you can bring some to class!


  7. This is soooo interesting! and you are taking it to the next level! great job!


  8. This is so very interesting – kind of like magic! And how does it taste – parang popping small liquid apples into the mouth? And I too am crazy about texture – is it like gelatin or sago? Yummmmm…


    • It tastes exactly like apple and the texture is that of caviar 😀 it pops! it has a thin layer of gel on the outside and the inside is pure liquid, texture is really that of caviar, hence the name 😀

    intriguing post! Congratz!!!! pataste ah!!! hahaha 😛


  10. can i get your contact for the alginate and calcium chloride?

    how much for both bags?


  11. wow. will try this. i’ve been to alyson’s. chemical haven. keep on posting stuff like this. nicey.

    kindly forward contact number of supplier of sodium alginate and calcium chloride.
    Thank you very much 🙂

    hi Hershey,

    May i please have the contact details of your supplier for sodium alginate and calcium chloride?

    I’ve been experimenting with spherification using either agar and carrageenan and dropping them in cold oil. Would like to experience the “liquid in liquid” result that accompanies the spherified algin in calci. Haven’t found any suppliers here in Baguio so I hope you will reply. Thanks so much in advance.

    Hi Hershey!

    Not sure if this blog is still active, but I’ve been trying to get a supplier for sodium alginate and calcium chloride. It would really help if you could send it to my e-mail. Pleaseeeeeeee 🙂

    Thanks a lot and happy eating 🙂
