In a blender, blend strawberries, lime juice, and rum. Pour into a glass and place in freezer.
Rinse out blender. Blend rum, pineapple juice, and cream of coconut.
Pour into glass, swirling if desired. Garnish with a slice of pineapple.
Notes
Rum: Use white rum. I like Bacardi.
Cream of Coconut: Look for this in the mixer aisle near the tonic water. Make sure to use cream of coconut, NOT coconut cream.
Lime Juice: For the best flavor, use freshly squeezed juice if possible.
To get the most juice from your lime, roll it on the counter and microwave for 20-30 seconds.
Get the Slushie Perfect Texture: If using frozen strawberries, use less ice to avoid a watery drink.
Laying Hack: Pour the second layer over the back of a spoon. This helps slow down the liquid and allows it to spread out without mixing the layers too much.
Store your glass in the freezer while you blend the second half to keep it icy cold.
