Begin by greasing silicone molds with coconut oil or lining a pan with greased wax or parchment paper.

In a heavy-bottomed pan, combine the sugar, ¾ cup of water, and citric acid. Bring to a gentle boil, then lower the heat.

Heat until the mixture reaches approximately 260ºF without stirring continuously.

Whisk together the cornstarch and ½ cup of water in a separate bowl until smooth.

Gradually drizzle the cornstarch mixture into the hot sugar syrup while stirring continuously until a gel-like consistency forms.

Return the combined mixture to low heat, stirring constantly until it becomes transparent.

Test for consistency by dipping a spoon into the mixture and placing it in ice water to gauge readiness.

Incorporate flavorings and colorings once the consistency is satisfactory, adjusting to taste.

Pour the mixture into the prepared molds and spread evenly. Allow to cool for several hours until set.

Once cooled, cut into small squares and dust generously with cornstarch to prevent sticking.
