Easy Kanten (Agar) Jelly Recipes: Basic, Coffee, Hojicha, and Lemon

These recipes are designed to be fail-proof. The key technique is always the same: whisk agar into cold liquid, bring to a boil, then simmer 1–2 minutes to dissolve fully.

1) Basic foolproof kanten (agar) jelly

Ingredients

• 500 ml water (or tea/coffee)
• 2.0 g agar powder (standard set)
• Sweetener to taste (optional)

Steps

1. Whisk agar into cold liquid.
2. Bring to a full boil, then simmer 1–2 minutes, stirring.
3. Add sweetener/flavor, stir well.
4. Pour into molds. Set at room temperature. Chill for a tighter bite if desired.

2) Coffee jelly (café-style)

Ingredients

• 500 ml strong coffee
• 2.0 g agar powder
• Sugar to taste

Tips

• Serve with milk or soy milk poured over cubes.
• For a softer texture, reduce agar slightly (e.g., 1.5 g).

3) Hojicha jelly (Japanese roasted tea)

Ingredients

• 500 ml strong hojicha (roasted green tea)
• 2.0 g agar powder
• Optional: a touch of honey or syrup

This one is great if you want a clean, aromatic jelly that pairs with fruit or sweet cream.

4) Lemon jelly (acid-safe method)

Important: Add lemon juice after agar is fully dissolved.

Ingredients

• 450 ml water (or mild tea)
• 2.0 g agar powder
• 50 ml lemon juice (adjust to taste)
• Sweetener to taste

Steps

1. Dissolve agar in the 450 ml base: boil, then simmer 1–2 minutes.
2. Turn off heat, let it cool slightly, then stir in lemon juice and sweetener.
3. Pour into molds and set.

5) Plating tips (make it look premium)

• Cut clean cubes with a wet knife.
• For clarity, avoid boiling too aggressively once dissolved (gentle simmer is enough).
• For layers, pour the next layer when the first is just barely set.

6) Storage

Keep in the refrigerator in a covered container. For best texture, enjoy within a few days.
