Find agar agar and decide which form works best for you. Agar agar usually comes in 3 forms: powder, flakes, or a bar. All 3 work equally well; the real difference is ease of preparation. Powdered agar agar is usually the easiest to use, as it can be substituted for gelatin in a 1:1 ratio (1 teaspoon, or about 3 g, of gelatin is equivalent to 1 teaspoon, or about 2 g, of agar agar powder). [1] X Research source The powder also dissolves more easily than flakes or bars. If you're not sure which type to use, default to the powdered agar agar.

Agar agar’s melting point (185 degrees) is much higher than gelatin’s (95 degrees). Therefore, you must boil agar agar to make it set. You only need to add gelatin to warm water.

If you are trying to jellify a somewhat acidic liquid, such as those derived from citrus fruits or strawberry, you may need to add more agar agar. [4] X Research source Finding agar agar was pretty difficult several years ago. But fortunately, it’s recently become more popular. You can usually find it at most major supermarkets.

National Library Board, Singapore. pp.20–23. Agar exhibits hysteresis because when mixed with water, it solidifies and forms a gel at about 32–42°C (305–315K; 90–108°F), which is called the gel point, and melts at 85°C (358K; 185°F), which is the melting point. [28] Hysteresis of agar occurs due to the difference between the gel point and melting point temperatures. [29] This property lends a suitable balance between easy melting and good gel stability at relatively high temperatures. [30] Since many scientific applications require incubation at temperatures close to human body temperature (37°C), agar is more appropriate than other solidifying agents that melt at this temperature, such as gelatin.

[46] Until recently, I was an agar-agar novice. I didn’t grow up eating gelatin desserts like many of my friends, and I never really liked things with a jiggly consistency on those few rare occasions I actually tried them. But while experimenting with a vegan cheese recipe for a VT story, I discovered this ingredient’s unique versatility. What Is Agar-Agar?
