I ran into the problem of having to come up with an alternative for pomegranate seeds for a relish today. I got online and found a recipe for making pomegranate caviar from gelatin rather than the sodium alginate and calcium chloride method. These are a little more firm than using the spherephication method, but works well since the dish require they be tossed with other ingredients before serving. The method consists of blooming the powdered gelatin (3tsp) with cold water (4Tbs). I then added heated pomegranate juice (3 oz) to the gelatin mixture and poured it into a squeeze bottle. I then dripped the mixture into chilled olive oil (grape seed oil works well with pomegranate). After just a moment the liquid firms up and simply straining the caviar from the oil finishes this component. It has held its shape now for several hours.
