Stovetop Fruit Jellies
Stovetop fruit jellies are made by reducing pureed fruit with a thickening agent like agar-agar or gelatin until the mixture sets firmly at room temperature or in the fridge. The process relies on bringing your liquid base to a simmer and ensuring your setting agent is fully hydrated before pouring it into a shallow mold to cool.
Consistency is your main hurdle.
Work quickly once your thickening agent hits the boiling fruit mixture, as it will start to set the moment the temperature drops. Have your mold ready and level before you even turn on the stove.
- small saucepan
- whisk
- silicone spatula
- 8x8 inch square glass dish
- fine mesh sieve
What goes in.
- 2 cupsfresh fruit puree (strawberries, raspberries, or mango)
- 2 tbspagar-agar powder
- 1/2 cupgranulated sugar
- 1 tsplemon juice
Blooming and Boiling
Agar-agar must reach a full boil to activate its setting properties. If you don't whisk it thoroughly while the liquid bubbles, you will end up with isolated clumps of powder rather than a smooth, firm jelly.
The method.
Prepare the fruit
Pulse your fruit in a blender until smooth, then push it through a fine mesh sieve into your saucepan to remove seeds and fibers.
Dissolve the solids
Whisk the sugar and agar-agar into the cold fruit puree. Do not turn on the heat until everything is combined and no dry streaks remain.
Boil the mixture
Place the pan over medium heat. Bring the mixture to a steady, rolling boil while whisking constantly for 3 minutes to ensure the agar-agar is fully activated.
Set the mold
Remove from heat, stir in the lemon juice, and immediately pour the liquid into your glass dish. Let it sit undisturbed at room temperature for 30 minutes, then move to the fridge to firm up completely.
Other turns to take.
Herbal infusion
Steep fresh basil or mint in the fruit puree while it warms, then strain it out before adding the setting agent.
Citrus zest
Add a teaspoon of finely grated zest into the finished mixture right before pouring to provide a sharp contrast to the sweetness.
When it doesn't go to plan.
Test the set by placing a small drop on a cold plate; if it solidifies within 30 seconds, your ratio is correct.
Avoid using acidic fruits like pineapple raw, as they can prevent the agar-agar from setting properly.
Cut the jellies while they are still slightly chilled for the cleanest edges on your cubes.
The ones that keep coming up.
Can I use gelatin instead of agar-agar?
Yes, but use three times the volume. Keep in mind that gelatin-based jellies will melt at room temperature, while agar-based ones will hold their shape in the heat.
Why did my jelly turn out rubbery?
You likely used too much agar-agar or boiled it for too long, causing too much water to evaporate. Start with the measured amount and whisk thoroughly.
