Method
Make the red swirl
- Cook the strawberries and sugar over medium heat for 5 minutes, stirring until softened and glossy (about 180–200°F). You should see thickened berry juices coating the spoon.
- Blend the cooked strawberries until smooth, then spread the sauce on a sheet pan and cool completely to room temperature.
Make the blue swirl
- Cook the blueberries and sugar over medium heat for 5 minutes, stirring until the berries burst and the mixture looks jammy (about 180–200°F).
- Blend the cooked blueberries until smooth, then cool completely to room temperature.
Make the vanilla ice cream base
- Whip the heavy cream until stiff peaks form, holding a peak when the whisk is lifted (about 3–5 minutes on medium-high).
- Fold in the sweetened condensed milk and vanilla extract until no streaks remain and the mixture looks thick and creamy.
Assemble and freeze
- Spread one-third of the ice cream mixture into a loaf pan and level the top.
- Drizzle the red and blue fruit sauces over the layer in thin ribbons.
- Repeat with another one-third of the ice cream mixture, then drizzle more red and blue fruit sauces.
- Repeat layers until all ice cream mixture and fruit sauces are used, then swirl gently with a knife to create marbled ribbons.
- Freeze at least 6 hours, until firm enough to scoop solidly.
- Scoop and garnish with fresh berries and red, white, and blue sprinkles before serving.
Notes
For clean swirls, cool both fruit sauces fully before assembling—warm sauce can melt the ice cream base. Keep leftovers covered in the freezer for up to 2 weeks. Freezing is yes (best texture within 2 weeks). Dietary swap: use half-and-half or light cream only if labeled for whipping, but the texture may be softer and less stable.
