If you have a culinary torch, quickly pass the flame through the surface of the gelatin mixture in the bowl (which must be heatproof, preferably glass or metal) to pop the bubbles for a smoother appearance. If you notice that the gelatin mixture in the bowl is setting up and forming lumps, bring the saucepan of water to a simmer and place the bowl on top, stirring occasionally, to gently melt the lumps. Make sure that the gelatin mixture doesn’t get too warm -- no more than body temperature.
