Adapted from a recipe in "The Gift of Southern Cooking" by Edna Lewis and Scott Peacock.
Using olive oil to oil the molds adds more flavor, but be aware it turns yellow when refrigerated; vegetable oil will remain clear. In my experience, the longer the aspic sits in the molds after it has set, the harder it is to un-mold. If serving these for a dinner party, don't wait until time to serve to un-mold -- do it ahead of time, plate the aspics, cover and refrigerate. To make the aspic in one big mold, instead of individual small servings, increase the gelatin by ½ to 1 Tablespoon to give it more stability.
