In a bowl, sprinkle the strawberries with the brown sugar, cinnamon and guajillo chile powder, and let sit for 30 minutes until soft and juicy. Gently mash with a potato masher.
Meanwhile, stir together the cream, vanilla, granulated sugar, lime juice, and salt. Freeze according to your ice cream maker’s instructions.
When the vanilla ice cream base is done, gently stir in the strawberries.
Notes
Guajillo chile powder can be found in some specialty markets, but it’s easy to make your own, too. To do this, remove the stems from 8 ounces of guajillo chiles and place in one layer on a baking sheet. Cook the chiles at 300° F for 5 minutes or until dry. Crumble the dried chiles into a bowl and then grind them in a spice grinder or blender.
