Heat 1 ½ cups of the water to a simmer, but don't allow it to boil. Add the powdered gelatin and stir the mixture to completely dissolve the solution. Remove the mixture from the heat and add the remainder of the distilled water.
Add 20 to 30 drops of the essential oil and a few drop of food coloring, if you like. If you use concentrated liquid potpourri, substitute it for the water. The procedure is the same.
Pour the mixture into the baby food jars and leave it overnight at room temperature to set up.
Wrap some colorful tissue paper, fabric or a doily around the jars and tie a ribbon around them for an attractive gift.
