Step 1

Combine the berries, sugar, and lemon juice in a saucepan over medium heat. Stir continuously while the sugar melts and the mixture comes to a boil.

Step 2

Reduce the heat to medium-low and continue cooking for about 8-10 minutes, until the strawberries are soft. Use a wooden spoon to smash the berries a bit as they are cooking.

Step 3

Place a fine mesh strainer over a large bowl and carefully pour the hot mixture through the sieve. Press down on the cooked berries in the strainer with a wooden spoon to extract as much of the sauce as possible.

Step 4

Cool completely before transferring the sauce to an airtight container and storing it in the refrigerator.
