Molecular Gastronomy / Cooking: BEST OF THE WEB sphericals, caviar & raviole recipes

Are you looking for a surprise element for your next dessert? Sphericals have a liquid centre encapsulated by a gel membrane. This is achieved by using sodium alginate which gels in the presence of calcium.

There are lots of videos and photos on the web showing how to make sphericals or raviole and caviar, but some are just repeating the same recipe as other websites, have no recipe details or they are in another language.

Here is a collation of the best sweet spherical, caviar and raviole recipes. For more information on each one click on the picture to go to the source.

Ten tips for making sphericals at home:

1. If using a sodium alginate bath make it a day ahead. To mix the sodium alginate with the water first combine it with some sugar, this helps it not to clump together. Sprinkle a little on top of the water, mix and repeat until it is all added then blend for at least 2 minutes. You will need to use a blender. Leave in the fridge overnight so all the air bubbles disappear and the sodium alginate can completely rehydrated. If you do not do this you will get air bubbles in your gel coating so it will not look smooth and shiny.

2. Test, test, test… if you are trying a new recipe pour some of your alginate or calcium bath into a small bowl and use it to test your spherical solution. If your solution does not become properly encapsulated in alginate gel it will disperse in the bath – making a mess. This methods saves you wasting the whole bath.

3. What if your sphericals are mishapen? If they flatten out before sinking you may need to make your mix thicker / heavier – play with the viscosity of the solution using xanthum gum to thicken it (remember a little goes a long way blend and leave for a couple of minutes). It could also be too high in fat or have too many little air bubbles both of which cause it to float. If you caviar is tadpole shaped check that it is not too thick and experiment with adjusting the height and angle of pipette. If your caviar is flat either thicken or drop from slightly higher so it penetrates the surface as it drops in.

4. If using an alginate bath (reverse spherification) do no allow your sphericals to touch while in the bath or they will gel together.

5. Use distilled water in the alginate bath – or the calcium in your tap water may cause it to gel.

6. The alginate gel is senstive to pH, it works best with pH 4.5 to 6. Click here for pH levels of foods. You can adjust the pH content by adding sodium citrate to the liquid base.

7. Alcohol breaks down the gel so if using in cocktails it will only work with drinks that are less than 20% alcohol.

8. Sodium alginate cannot be dissolved in oil.

9. If it is not forming a gel and when you stir it the mixture just disperses in the bath or it forms a weak gel that breaks as soon as you lift it out of the bath – check the amount of additives, check the pH of the solution, look at the fat and alcohol content of ingredients in your recipe.

10. To get perfect spheres freeze the sauce in a spherical mould and then place in a warm bath to encapsulate.

    I need help with dehydrating a compound butter I made with fresh fruits.
    I am attempting to use these for the beurrage in croissants and other laminated baked goods. I want to use the least amount of having to add flour/icing sugar as compensation to the increase of liquid from the juice of the fruit. Peaches are my biggest nemesis currently.
    I am using (uber expensive) 86% butterfat butter trying to help balance this increase of liquid. Any thoughts?
    If nothing else I have some amazing fruit compound butters for, well just about everything.

    • Hi Mallissa, Have you tried using freeze dried strawberries?. Perhaps you could put them in a blender and turn them into a powder – that way you are not adding any liquid. As for decreasing the liquid in the butter that you already have the only way I can think of is heating it to melt the butter and keep heating over low heat to let the liquid evaporate, but that will change the flavour of the butter.

  3. hi dear ann… finally i can find calcium lactat… but i dont have sodium alginat… can i make some dessert whit that?

  5. I just purchased some of these chemicals used in Molecular Gastronomy & tried out some recipes. Unfortunately the recipe for plain Spherification using Calcium lactate bath for making Cocoa Caviar(which i got from another site that follows the exact same measurements as Mint Caviar) did not turn out as expected:( I Instead of getting perfectly round sphericals i’m chunks of cocoa across the bath. And when i tried making Drinkable Yogurt Ravioles using Sodium Alginate the same happened:((( I really don’t get what went wrong as i followed the entire recipe to the T including the measurements. If you could suggest any tips i would be very grateful, because i need to present these pretty soon.

    • Hi Shayoni, The higher fat content of some ingredients can impact the process significantly. This sounds like it has caused you problems with your cocoa caviar. With the yoghurt Ravioles, Ann recommends To get perfect spheres, freeze the sauce in a spherical mould and then place in a warm bath to encapsulate. You could check out the updated recipe here for Mango Lime sphericals :

  6. Im looking to make the coconut sphere, what does ‘cl’ stand for next to the coconut cream amount, thankyou!

    • sorry, also.. when there is water in the flavoured liquid can you just use normal tap or filtered water? rather than distilled? or does it affect the reaction still. thanks again!

      • Hi Kasey, It’s best to use distilled water for best results.

  7. I am interested in making the chocolate sphericals however the recipe above is just a duplicate of the custard spherical. Could you provide the recipe for the chocolate ones? Thanks so much!

    • Great pick up Beth. I have updated the method. You will also find the title link for the chocolate spherical on this page, will take you to a more detailed explanation and the correct method. Have fun making these!

  8. I am interested in making the chocolate sphericals but the directions seem to be directions for the custard sphericals. Can you provide the recipe for the chocolate ones? Thanks!

  9. how far in advance can I make raspberry raviolis, I am planning an event so I could use as much pre-prep time as possible. thanks!

    • Hi bonnie, you can make them up to half a day ahead and leave in liquid, so they don’t dry out. Please not that if you do that some of the raspberry can leach out into the liquid and vice versa so I suggest a sweet simple syrup is best.

  10. Hi, I’m trying to make raspberry caviar. I have everything I should need but it doesn’t seem to woke. The recipe I am using is 2g sodium alginate to 450 Ml water. Then 500ml of raspberry puree to 5g calcium lactate. Dropping them in with pipettes, but no gel seems. Doing reverse spherification. Can you help me?

    • Hi dan, I think your calcium is too low in the raspberries. 120ml of raspberry puree needs 1/2 teaspoon of calcium lactate.
      Aslo caviar is usually done the other way putting the calcium in the bath and the alginate in your raspberry so the raspberry gels. The way you are trying to do it a membrane will form on the outside of the tiny caviars making them look chunky. If I was you I’d add more calcium salts and make sphericals with what you’ve got and then try the other way for caviar.

  11. I purchased Jacquard Sodium Alginate, I wonder is it safe for cooking? Are all sodium alginates safe to eat?

  12. i just got a kit- looking forward to play with it. my culinary instructors will have heart attack- ha ha!

    • Have fun Mia, if you come up with some fantastic new recipes share them here for us all to try.
