Toast the Pecans
- Heat a skillet over medium heat and melt 2 tablespoons of butter.
- Add 1 cup of chopped pecans and stir frequently to prevent burning.
- Toast until the pecans are golden brown and fragrant, about 5-7 minutes.
- Remove from heat and let the pecans cool.
Prepare the Custard Base
- In a medium saucepan, combine 2 cups heavy cream and 1 cup unsweetened almond milk. Heat over medium-low heat until it just begins to simmer.
- In a separate bowl, whisk 4 egg yolks until pale and thickened.
- Gradually pour the hot cream mixture into the egg yolks, whisking constantly to prevent scrambling.
- Return the mixture to the saucepan and cook over low heat, stirring constantly, until the custard thickens enough to coat the back of a spoon, about 8-10 minutes.
- Remove from heat and stir in 1/2 cup keto-friendly sweetened condensed milk, 1 teaspoon vanilla extract, and a pinch of salt.
- Allow the custard to cool to room temperature, then cover and refrigerate for at least 2 hours, or until thoroughly chilled.
Churn the Ice Cream
- Pour the chilled custard into your ice cream maker.
- Churn according to the manufacturer’s instructions, usually 20-30 minutes.
- During the last few minutes of churning, add the toasted pecans.
Freeze the Ice Cream
- Transfer the churned ice cream into an airtight container.
- Cover the surface with plastic wrap to prevent ice crystals from forming.
- Freeze for at least 4 hours, or until the ice cream is firm.
