Apple Juice Caviar (and Fruit Juice Caviar)

Fruit Juice caviar consists of small, bead-like spheres of fruit juice, encased in a thin gelatinous membrane. The recipe here for apple juice caviar is one such example and it can be made with other fruit juices for a variety of juice caviars. 

When bitten into the gelatinous pearls release the juice contained within, offering a sudden burst of flavor. Resembling real caviar in appearance, fruit juice caviar adds a touch of elegance and fun to various dishes and drinks. 

I am going to describe the more difficult process of making apple juice caviar, but then give a “cheater” easier way to do it.  

The Science Behind the Spheres

The more difficult way to create fruit juice caviar predominantly involves a technique called spherification, a molecular gastronomy process. There are two main types of spherification: basic and reverse.

1. Basic Spherification: In this method, the fruit juice is mixed with sodium alginate, a natural substance derived from brown seaweed. This mixture is then dropped into a bath of calcium chloride or lactate, where it forms small beads. The calcium ions cause the alginate to gel, encapsulating the juice inside.
2. Reverse Spherification: This method is often preferred for liquids with high calcium content or when a better sphere texture is desired. In reverse spherification, the calcium is mixed with the juice, and then the mixture is dropped into a bath containing sodium alginate.

Both methods result in the formation of spheres with a liquid core and a gelled outer layer. The thickness of the membrane and the texture of the caviar can be adjusted by altering the duration the droplets remain in the bath.

You can see a good example of the above method using mango juice here.  

Here are also instructions for the more difficult method, but this is one which will more likely result in a spree that bursts and resales juice.   

Ingredients needed to make Apple Juice Caviar:

For the caviar:

300 ml apple juice
5 drops red food colouring
20 gm caster sugar
3 gm sodium alginate

For the calcium bath:

5 gm calcium chloride
500 ml water
10 drops red food colouring

For storage:

250 ml apple juice
Few drops red food colouring
Cooking instructions for Apple Juice Caviar:
Place the sugar in a bowl and stir in sodium alginate until well mixed.
Drizzle the apple juice over the mixture gradually, while whisking it at the same time until they blend together to form a smooth mixture.
Stir in a splash of the food colouring and continue to whisk the mixture with an electric mixer for about 5 minutes at lowest possible speed.
Set it aside for 10 minutes or until it turns into a gel.
To make the calcium bath, pour the water in a bowl and stir in the calcium chloride and a splash of food colouring into it until the chemical dissolves and is mixed thoroughly.
Set 250 ml apple juice aside in a separate bowl.
Fill a syringe with the apple juice gel and squeeze out small, regular drops of it into the calcium bath, with its tip pointed about 10 cm from the bowl.
Swirl the calcium water all this time to allow the gel to form globules.
Leave them in the calcium bath for 3 minutes and scoop them out with a strainer into the bowl with apple juice; don’t keep the caviar for more than 3 minutes or they will become tough.
Stir in few drops of food colouring gently into the storage fruit juice and preserve the caviars in them for as long as a couple of days when kept in a refrigerator.
Use it to top desserts, pate, sushi or grilled food and enjoy!

An Easier way to Make Fruit Juice Caviar

The spheres will come out more solid, but the easier way to make fruit juice caviar is the use agar (a plant-based gelatin) or gelatin to make the spheres.   The juice is mixed with the agar and dropped into oil from a syringe, where if forms the caviar spheres.

For apple juice caviar the ingredients needed would be 1/2 cup of a mild, flavorless oil, that remains liquid when chilled. Vegetable oil or Sunflower oil are good choices. Olive oil is not as it solidifies when chilled and has flavor. 1/3 cup apple juice or other fruit juice, and 1/4 teaspoon agar powder. 

The juice is mixed with the agar and brought to a boil.. Then using a syringe, the juice is slowly dropped into chilled oil, where it solidifies. From there it can be gently strained to release the spheres.   

Applications and Pairings For Apple Juice Caviar

The versatility of fruit juice caviar makes it suitable for numerous culinary applications:

1. Desserts: They can be sprinkled over cakes, ice creams, or puddings to add a surprise element and enhance the dish’s visual appeal.
2. Beverages: Imagine sipping on a cocktail or mocktail that has these tiny beads, providing intermittent bursts of fresh juice flavor.
3. Salads: They can be used as a garnish to add an exciting twist to your regular salads.
4. Appetizers: Elevate the experience of your guests by using fruit juice caviar as a garnish for canapés or starters.

For example, try serving them with Es Cendol or Es Teler for a very unique combo. 

A Gourmet Experience at Home

Making fruit juice caviar is not as daunting as it sounds. With a few ingredients and some basic equipment, you can whip up your own batch of these flavorful pearls.

To achieve the best results, ensure you have:

1. Accurate measurements of ingredients.
2. A proper sieve or dropper to form uniform droplets.
3. Cold oil or an ice bath to halt the gelling process if needed.
4. A fine mesh strainer to collect the formed caviar.
