The mixture is made using just two ingredients—unflavored powdered gelatin and water—and then poured into arts & craft store-variety silicone LEGO molds or ice cube trays.
You need simply mix the powder with water and melt the mixture. Thompson recommends letting it sit for ten minutes and then pouring the jelly-to-be into a squeezable condiment container to easily dispense it into the molds.
If lumps form, pour the entire mixture into a large drinking glass, where air bubbles and clumps will rise to the top, adding more water if you desire clearer bricks, and increasing the ratio of unflavored gelatin to flavored for a chewier texture. Allow five hours for the syrup to cool. Provided that the mixture properly fills the mold, the resulting LEGO bricks and figures should be stackable just like the real toy—veritable proof that everything is awesome, as proclaimed by the irritatingly catchy LEGO Movie theme song.
