Method
- Combine 2 cups of heavy cream and the sugar in a saucepan. If using a vanilla bean, split it and scrape the seeds into the cream now.
- Place the saucepan over medium heat and stir constantly until the sugar is completely dissolved and the cream is scalding hot (look for tiny bubbles around the edges, but do not let it boil).
- Remove from heat. If you used a vanilla bean, let it steep in the hot cream for 10 minutes to extract the flavor.
- Stir in the remaining 2 cups of cold heavy cream. If you are using vanilla extract instead of a bean, stir it in now.
- Cover and refrigerate the mixture until it is completely chilled (at least 4 hours, or overnight for the best results).
- Pour the cold mixture into your ice cream maker and churn according to the manufacturer's directions. Stop the machine when the ice cream reaches a thick, soft-serve consistency.
- Transfer the ice cream to a freezer-safe container, smooth the top, and freeze for at least 4 hours to "ripen" and reach its final, velvety texture.
Notes
1. The Scalding Science: Do not skip the scalding step. Heating half of the cream to just below a boil (around 180°F) denatures the whey proteins. This acts as a natural stabilizer, which is the "1913 secret" to a smooth, velvety texture without using eggs or chemical thickeners.
2. Vanilla Substitution: While pure vanilla extract is standard for modern convenience, using a whole vanilla bean provides the most authentic Philadelphia-style experience. If using a bean, ensure you split and scrape the seeds into the cream before scalding to allow the flavor to infuse properly.
3. The "Ripening" Phase: For the best result, allow the churned ice cream to "ripen" in the freezer for at least 4 hours. This 1913 technique allows the moisture to stabilize and the flavors to deepen, resulting in a much denser, professional-quality scoop.
4. Temperature Control: Ensure your cream mixture is completely cold (refrigerated for at least 4 hours) before pouring it into your ice cream maker. If the mixture is even slightly warm, it may result in a "buttery" or grainy texture rather than a smooth one.
