Chef's Tips
Use freshly squeezed, well strained lemon juice for the brightest flavour and smoothest gel.
Bring the lemon juice to a full boil after adding the agar to properly activate the gelling power.
Let the gel set fully in the fridge before blending, otherwise it will stay runny instead of forming a smooth gel.
For a firmer gel that holds sharper dots, increase the agar slightly; for a softer gel, reduce it by 1 to 2 grams.
Store the blended gel in a piping bag or squeeze bottle to make plating clean and precise.

Instructions
Lemon Gel
- 1
Pour the lemon juice into a small saucepan and weigh out the sugar and agar powder separately.
- 2
In a small bowl, whisk the superfine sugar and agar powder together to disperse the agar evenly.
- 3
Heat the lemon juice over medium heat until steaming, then sprinkle in the sugar–agar mixture while whisking constantly.
- 4
Bring the mixture to a full boil and let it bubble for 1 to 2 minutes, whisking, to fully activate the agar.
- 5
Remove from the heat, skim any foam if needed, and pour the mixture into a shallow container. Let it cool to room temperature, then refrigerate until fully set into a firm gel.
- 6
Once set, cut the gel into cubes, transfer to a food processor and blend until completely smooth and glossy.
- 7
Use immediately or store refrigerated in a sealed container, piping bag or squeeze bottle.

Sharp Lemon Agar Gel
Sharp Lemon Agar Gel
This lemon gel is made with lemon juice, sugar, and agar for a firm set that can be blended smooth after chilling. It works well for tart finishing, plated desserts, and layered pastry components where you want a clear citrus element.
Main Characteristics
Main Characteristics
Agar gives the gel a stable structure after boiling and cooling. Once blended, the texture becomes smooth enough for piping dots, short lines, or spooned accents. The flavour stays direct and acidic, so smaller amounts are usually enough.
Texture Control
Texture Control
- Increase the agar slightly if you want a firmer gel for cleaner dots.
- Reduce the agar slightly if you want a softer finish for spooning or spreading.
- Blend thoroughly after the gel is fully chilled to remove any small lumps.
Uses
Uses
- Pipe around lemon or berry tarts
- Add to cheesecake plates
- Spoon alongside panna cotta
- Layer into citrus-based entremets
- Pair with vanilla, coconut, white chocolate, or fresh berries
Storage Notes
Storage Notes
Store the blended gel in the refrigerator for up to 5 days in a sealed container, piping bag, or squeeze bottle. If it firms up during storage, blend or whisk briefly before using.

· 7 Sept 2025I love that it is naturally vegan. I reduced the agar slightly for a softer consistency and it still held a nice shape.
Kenji
· 29 Jun 2025Used this as a garnish for a cheesecake plate. The agar set really well and stayed stable even at room temperature.
Marta
· 18 Apr 2025Sharp lemon flavour and a clean texture. It piped well as small dots around a lemon tart.
