Warm the heavy cream and almond milk over medium-low heat until steaming. Remove from the heat, add the basil leaves, cover, and steep for 15 minutes.
Whisk the egg yolks, allulose, lemon juice, and lemon zest in a small saucepan over medium-low heat. Cook until the curd coats the back of a spoon, then remove from the heat and whisk in the butter.
Press the lemon curd through a fine-mesh strainer and refrigerate it until completely cold.
Strain the basil-infused cream, then blend it with the powdered allulose, mascarpone cheese, vanilla extract, xanthan gum, and sea salt. Refrigerate for at least 3 hours.
Churn the basil mixture in an ice cream maker according to the manufacturer's directions until thick and creamy.
Layer the ice cream with spoonfuls of lemon curd in a freezer-safe container. Freeze for 3 to 4 hours before serving.
