Kanten is a delightful and refreshing Japanese dessert that is both light and satisfying. Made with agar-agar powder, this jelly-like treat is perfect for those looking for a vegan and gluten-free option. The subtle sweetness and hint of vanilla extract make it a versatile dessert that can be enjoyed on its own or paired with fruits and syrups.
Agar-agar powder is a key ingredient in this recipe and may not be commonly found in every household. It is a gelatinous substance derived from seaweed and is often used as a vegetarian alternative to gelatin. You can find it in the baking or health food section of most supermarkets, or at specialty Asian grocery stores.

Ingredients For Kanten Recipe
Agar-agar powder: A gelatinous substance derived from seaweed, used as a vegetarian alternative to gelatin.
Water: The base liquid for dissolving the agar-agar powder.
Sugar: Adds sweetness to the kanten.
Vanilla extract: Provides a subtle vanilla flavor to the dessert.
Technique Tip for This Recipe
When working with agar-agar powder, ensure it is fully dissolved in the water before bringing it to a boil. This prevents any lumps from forming and ensures a smooth texture. Stirring constantly while heating is crucial to avoid any clumping. Once you add the sugar, make sure it is completely dissolved before removing from heat. Adding the vanilla extract off the heat preserves its delicate flavor. When pouring the mixture into a mold, do so slowly to avoid air bubbles, which can affect the final appearance of the kanten.

How to Reheat Leftovers
Steaming Method: Place the kanten in a heatproof dish and set it in a steamer basket over boiling water. Cover and steam for about 5-7 minutes until it’s warmed through. This method helps retain the texture and flavor.
Microwave Method: Place the kanten on a microwave-safe plate. Cover with a microwave-safe lid or plastic wrap to prevent drying out. Heat on medium power for 20-30 seconds. Check and repeat if necessary, but be careful not to overheat as it can alter the texture.
Hot Water Bath: Fill a large bowl with hot water (not boiling). Place the container of kanten into the hot water, ensuring the water level is below the rim of the container. Let it sit for 5-10 minutes, stirring occasionally to ensure even warming.
Oven Method: Preheat your oven to 150°C (300°F). Place the kanten in an oven-safe dish, cover with aluminum foil to prevent drying out, and heat for about 10 minutes. Check to ensure it’s warmed through.
Room Temperature Method: If you prefer not to use heat, simply let the kanten sit at room temperature for about 30 minutes to take the chill off. This method is gentle and preserves the original texture.
