Florida Orange Jelly

Gelatin proteins form a three-dimensional network that traps liquid, creating the signature firm yet jiggly texture of a molded jelly. The pectin naturally present in citrus rinds works synergistically with the gelatin to strengthen the gel structure. Boiling the juice, sugar, and rinds together concentrates flavors through water evaporation while the heat extracts essential oils from the citrus zest, creating a more aromatic and complex preserve. The acidic citrus juice actually helps stabilize the gelatin structure, preventing it from becoming rubbery.
