Start by pouring your favorite fruit juice into a medium-sized saucepan. If you desire added sweetness, sprinkle in the sugar and stir gently until fully dissolved.

Next, sprinkle the agar agar powder into the juice. Place the saucepan over medium heat and bring the mixture to a gentle boil while continuously stirring.

Once boiling, reduce the heat to low and continue cooking for an additional 4 minutes while whisking constantly.

Carefully pour the hot vegan jello mixture into your chosen glassware or molds.

Place the filled molds in the refrigerator and allow them to chill for at least 2 hours.

Once the jello has fully set, carefully release it from the molds or serve directly in the glasses.
