Parkinson's Pure Vanilla Flavoring

Parkinson was the unrivaled expert at crafting Philadelphia style ice cream, also called custard cream or Philadelphia cream, often considered the prototype of frozen desserts in America. During the second half of the nineteenth century, his ice cream was renowned as the best of the best—not only in Philadelphia, but throughout the United States. A staunch advocate for American foods, Parkinson boasted that the smooth and creamy ices made from rich Philadelphia cream were unique and original, a product of the region’s fertile bounty. “This delicious dish smacked of the fat of the land,” he said.
 
The recipe I tried today came straight out of an 1876 issue of Confectioners’ Journal (a publication edited by Parkinson).  The original is as follows:
 
Vanilla – When vanilla bean is used for flavoring, prepare it by cutting in small pieces, and boiling in a small amount of milk or cream to extract the flavor; then pour into the cream, to which add one-third pound of white sugar to each quart of cream, and strain into the can. One vanilla bean is sufficient for four quarts of cream.
 
My updated version:
 
Parkinson's Vanilla Ice Cream

• ½ vanilla bean
• 1 quart heavy cream
• ½-2/3 cups sugar

1. Pour a little milk or cream into a small saucepan. Scrape seeds from vanilla bean into cream and heat briefly to release the flavor.
2. Pour cream into the freezer bowl of an ice cream maker. Add sugar to taste and the vanilla seed-infused cream, straining through a fine sieve if desired.
3. Mix until thickened, about 20-30 minutes.
4. The ice cream will have a soft, creamy texture. Feel free to eat right away or transfer to a glass bowl with a lid and place in the freezer until firm.
