Derived from seaweed, agar agar serves as a vegan gelatin substitute that dessert enthusiasts often use. While several other substitutes are available to replace gelatin in desserts, agar agar is often considered the best alternative. One typically needs just one-third of agar agar to replace one whole part of gelatin. For activation, agar agar needs to be boiled in liquid for 3-5 minutes before using it in the dessert recipe. This one is an excellent choice for jellies and other fruit-based desserts.
It's a plant-based hydrocolloid extracted from seaweed. Widely used in Asian cuisine, it creates a firm yet delicate texture in desserts. This plant-based gelatin substitute, derived from red seaweed, is an extremely strong alternative to gelatin.
Unlike gelatin, agar agar is entirely vegan-friendly, making it an ideal choice for those adhering to plant-based diets.
Dietary Suitability: Agar is a vegan setting agent of plant (seaweed) origin, whereas gelatin is derived from animal collagen.
Texture: Agar needs to be boiled as it sets at high temperatures and ideally maintains a firm texture at room temperature. Gelatin, on the other hand, melts at body temperature.
Setting Strength: With clear differences in origin,agar’s texture is brittle, firm, and slightly crunchy, while gelatin features a soft, creamy, and elastic gel texture.
Usage: Agar needs to be boiled to activate, while gelatin only needs to be dissolved in warm water.
There are three forms of agar agar available on the market:
Powder: The easiest type that dissolves fast and is most convenient to use.
Flakes: Larger, more bulky pieces that take longer to cook and use more product.
Strips or bars: Traditional dried sheets of agar agar that require soaking before cooking.
Since the concentrations of the different types are not equal, it is important to know the conversions. One teaspoon of agar agar powder is equivalent to one tablespoon of agar agar flakes. But to be sure, it is better to check the recommendations for each package.
The activation of agar agar occurs only when it is boiled. Heating agar in liquid will not completely dissolve it.
After being brought to a boil, the dessert mixture starts to set at a temperature range between 35°C and 45°C. As opposed to gelatin, agar can set up not only in the fridge but at room temperature as well.
After setting, agar remains a solid mass until it reaches 85°C or above. This allows desserts made from agar agar to stay firm when being served or transported.
Several components play an important role in creating a good texture of an agar dessert. Knowing their interaction allows for more predictable results.
The ratio of the components influences how strong or fragile the final dessert is.
When there is too little agar agar, the result is a loose or fragile gel that does not hold its shape. On the other hand, too much agar agar will make the dessert rubbery and too firm.
For most of the recipes, a balanced ratio will work fine. For delicate puddings, use less agar; for jellies and decorative inserts, use more.
Proper measurement is essential since even minor changes in the amount will affect the dessert's consistency.
Sugar softens the agar agar gel making the dessert fragile. For high-sugar recipes, a slight increase in the amount of the agar may be required.
Acidic components like lemon juice, lime juice, passion fruit, and vinegar can inhibit the gelling properties of agar agar if it is added too early during cooking.
To ensure the best effect, agar agar should be dissolved and activated first. Later, when the mixture has already cooled down, the acidic ingredients can be added.
Agar agar works well with milk, cream, yogurt, and coconut milk.
When using dairy products, it is advised to add them only after all the agar agar has been dissolved to avoid a lumpy texture.
All fruits can be used in agar agar recipes, except those with high acidity, which can affect the gel's quality. Mixing fruits with the dissolved and activated agar-agar will yield more successful desserts.
To achieve the best results with agar agar, it is important to follow several rules.
The first step is measuring the required amount of agar agar based on the recipe.
Then whisk the component in cold liquid to distribute it evenly.
Heat the mixture until it boils and stir for one or two minutes to make the agar agar fully dissolved.
Skipping the boiling step can lead to undesired result – the grainy texture and poor setting.
When all the agar is dissolved, add the rest of the ingredients into the warm mixture.
Act quickly because agar starts to set when the temperature decreases. When waiting too long, the mixture may thicken before adding everything else.
Stir all the other ingredients constantly to keep the texture even.
If the setting of the gel starts, heat it again to make it liquid.
Pour the prepared mixture into the dessert glasses, molds, or dessert rings.
Let it cool down at room temperature. Most of the agar agar desserts start to set right away and become fully firm quite quickly.
It is not always necessary to put it into the fridge. But doing this will improve the taste and give a refreshing feeling in puddings, jellies, and layered desserts.
Do not disturb the dessert while it is setting.
