Step 1: Combine the strawberries, sugar, and lemon juice in a large, heavy-bottomed pot.
Step 2: Let the mixture sit for at least 2 hours at room temperature to allow the fruit to macerate and release its juices.
Step 3: Place a small plate in the freezer to use later for testing the set point of your strawberry preserves recipe.
Step 4: Bring the strawberry mixture to a boil over medium heat, stirring constantly until the sugar has fully dissolved.
Step 5: Increase the heat slightly and maintain a rolling boil for about 20-30 minutes, skimming off any pink foam that rises to the surface.
Step 6: Test for doneness by dropping a small spoonful of preserves onto the chilled plate; if it wrinkles when nudged, it is ready.
Step 7: Ladle the hot preserves into sterilized jars, leaving 1/4 inch of headspace, and seal tightly.
