Thaw the frozen strawberries completely, keeping all of the juice released as they thaw.
Add the thawed strawberries, their juice, and the beef gelatin to a high-powered blender.
Blend until completely smooth and the gelatin is evenly distributed, stopping to scrape down the blender if needed.
Transfer the mixture to a microwave-safe bowl.
Microwave for 15 seconds to gently warm the mixture. Do not boil.
Stir thoroughly until the mixture looks smooth and uniform.
Place a silicone mold on a firm tray, then pour the strawberry mixture evenly into the mold.
Refrigerate for 2–4 hours, or until completely firm.
Gently remove the gummies from the mold and store them in an airtight container in the refrigerator.
