Coffee Caviar

Caviar | Coffee caviar is a fun little kitchen science experiment you can try with kids. It will be a fun project and you will have a delicious desert topping at the end of the day.

What is coffee caviar?

Caviar is nothing more than turning liquids into solids using the method of molecular gastronomy. Coffee caviar is made by turning black coffee into a small spherical shape. To make it, use simple ingredients such as cold oil and agar agar. Usually caviar is produced using sodium alginate and calcium chloride. But this is done using agar agar and cold oil.

Coffee caviar adds a nice touch to this plated desert. It looks nice and adds balance and burst of coffee flavor. It is nothing more than sweetened black coffee thickened with an agar agar mixture. This is then poured into a dropper and transformed into caviar by dropping it into cold oil. It’s a fun process and in this same recipe, instead of coffee, you can use any fruit juice.

Making it was a lot of fun and not difficult at all! And it’s not just aesthetic, it’s tasty too! I made this caviar act as a component with mine mocha paradise desert. I really loved the balance that the caviar brought to the entire dessert.

The caviar itself was not sweet at all. When you spooned it it added a burst of coffee flavor.

Coffee caviar ingredients

Black coffee – I used a strong cup of black (American) coffee to make this coffee caviar. You can use instant coffee powder and mix it with water too. Instead of coffee you can also use fruit juice.

Sugar – a small touch of sugar is added to sweeten the coffee.

Jelly – agar agar is the important ingredient in the preparation of coffee caviar. Agar agar is mixed with fruit juice or black coffee and poured into a dropper bottle. When we put the liquid into cold oil, it takes on a spherical shape.

Oil – I used neutral tasting oil such as refined oil or sunflower oil. Some other oils freeze at low temperatures, such as coconut oil, which is not recommended.
