Imperial JelloThere is nothing like a Jello mold for a great visual impact and taste of Americana. I don't favor the lime Jello with the grated cabbage, which is just a sneaky device to get vegetables into reluctant kids in my opinion. I want bells and whistles with lots of production quality.

Some years ago I found a recipe in Jane and Michael Stern's
Real American Food, which seems to be the cookbook companion to
Roadfood Goodfood. I have never made the recipe precisely as stated because I don't like canned cherries too much. Freshly frozen raspberries or canned mandarin oranges is quite another story, I like those ever so much.
Raspberry Imperial Jello
1/2 cup milk
1/4 cup sugar
1/2 teaspoon vanilla extract
1 tablespoon plus 1 teaspoon unflavored gelatin
2 tablespoons plus 2 teaspoons cold water
1/2 cup sour cream
2 large containers of raspberries packed in sugar
1 3-ounce package raspberry jello
dash salt
1 cup boiling water
3/4 cup heavy cream
Soften 1/2 tablespoon unflavored gelatin in 1 tablespoon cold water. Combine a saucepan milk, sugar and vanilla, then warm over medium heat until the sugar is dissolved. Remove saucepan from burner, add the softened gelatin and stir until dissolved. Cool to room temperature, the add the sour cream until it is thoroughly blended. Pour mixture into an 8-inch cake pan and chill.
Drain raspberries and put aside. Measure one cup of the reserved syrup, either adding water or putting aside any extra syrup. Heat the reserved syrup to boiling, then add raspberry Jello, salt and lemon juice. Soften remaining unflavored gelatin in remaining 2 teaspoons cold water, added to hot Jello and stir until dissolved. Measure 1/2 cup reserved syrup or cold water and added to Jello. Chill in a bowl until it reaches the consistency of egg whites.
Cut the refrigerated vanilla cream into 1/2 inch cubes, then set aside.
Whip the cream then add the jello, which is the consistency of egg whites, to the whipped cream and beat until smooth. Add the drained raspberries and vanilla-cream cubes, mixing very gently to avoid breaking the cubes.
Pour Jello into a 4-cup mold and chill until set.
Unmold by placing mold in warm water in the sink for 20-30 seconds, depending on water temperature, then slide your serving plate on top and flip. If it doesn't drop down, then return to the warm water for a bit longer.
Variations: I will use canned mandarin oranges and orange jello instead of raspberry; which looks like orange cream ice cream and tastes better. I have also made a strawberry variant, which was fine though not as good as the raspberry. I could see making one from fruit cocktail and peaches, using a peach jello as the base. The fruit cocktail now that I think of it would look really cool.
*I allowed the Jello to harden just beyond egg white consistency and didn't have the patience to melt it properly. A happy mistake which produced a mosaic look.
My extended family loves this Jello mold. I started years ago with placing only one on the Thanksgiving table, which disapeered promptly. The next year, I made two and lucked out on getting a small bite. I now make 3, which seems to allow most everyone to get a fair shake at it.
A friend from Culinary Historians is pretty expert on the history of Jello. She claims Royal Jello has better flavors when compared to like flavors of Jell-O. Though I haven't done a 1:1 comparison I have switched where I can to Royal.
More to come as I have time!
