Step 1

Combine frozen fruit, sugar, and salt in a saucepan over medium heat. Stir to combine, and heat until fruit is thawed and just warmed through, about 5 minutes. Do not boil.

Step 2

Transfer to the bowl of a small food processor. Blend until smooth, 15 to 20 seconds.

Step 3

Strain mixture using a fine-mesh strainer, pressing solids with the back of a spoon. Stir lemon juice into the coulis and serve.
