Brew chamomile and lavender teas, then let them cool slightly so they are warm but not hot.

Measure 100 ml chamomile tea and 20 ml very weak lavender tea into a small saucepan.

Warm the teas over low heat until steaming but not boiling, stirring occasionally.

Remove the saucepan from the heat.

Sprinkle the agar-agar powder evenly over the surface of the warm tea mixture.

Whisk steadily for 1 to 2 minutes, until the agar-agar is completely dissolved and the mixture is smooth.

Pour the liquid into silicone molds or a shallow glass dish, working quickly before it begins to thicken.

Transfer the molds or dish to the refrigerator and chill for 3 hours, or until the gummies are firm and set.

Pop the gummies out of the molds, or if using a dish, loosen the sheet, remove it, and cut into small bite-size pieces.

Store the gummies in an airtight container in the refrigerator until ready to serve.
