Combine the rosé wine, Aperol, and Blanc vermouth in a pitcher, stir until they are fully mixed, and then pour into the 9x13 baking pan. Note: Reserve about ½ cup of rosé for making the frosé (in step 4).
Place the baking pan in a level spot in the freezer for at least 8 hours, but 12 is better and overnight is ideal.
Using a rubber spatula, lightly break up the frozen rosé mixture in the pan, then carefully transfer it to the blender. Add the frozen strawberries, frozen pineapple, and lime juice to the blender.
Start the blender on low, pushing the fruit from the top carefully down into the alcohol mixture adding a splash or two of rosé to help everything come together.
Once combined, run your blender on high for 15 seconds or so to aerate the mixture a bit which lightens the texture.
Pour 4-6 ounces for a serving in the festive glass of your choosing and garnish.
