Place the 2 cups of strawberries and lemon juice in a medium saucepan. Turn the burner on to medium heat. Using a spatula stir the berries and lemon juice allowing the juices to release from the strawberries.
Once the strawberries are starting to fall apart, using a potato masher, mash the strawberries slightly.
In a small bowl (like a cereal bowl or pinch bowl) add the cornstarch and water, using a small whisk or fork stir until the water and cornstarch are combined.
Add the cornstarch slurry to the strawberry mixture. Stir to combine,
Next add the sugar and salt to the mixture. Allow the mixture to come to a slight boil but make sure to stir constantly.
Now that the strawberry mixture has thickened you’ll want to transfer the sauce to a medium sized bowl and place on the counter for about 30 minutes to cool, then place it in the fridge so it can cool down more. **The strawberry mixture needs to be cooled before placing it on the dough, it will affect the dough causing it to split and make it hard to roll up.
Line a 9x13 casserole dish with a piece of parchment paper and then spray with some baking spray and set aside.
Prepare the fresh strawberries, if using, by removing the tops and slicing them into rings. Place them in a bowl and set aside to use a little later.
Once the dough has doubled in size, place the dough onto a lightly floured surface. Roll the dough into a 15”x20” rectangle (about double the size of your casserole dish). The dough will be about ¾” thick.
Spoon the strawberry mixture onto the rolled out dough. Using an offset spatula, butter knife, or spatula, spread out strawberry mixture over the top of the dough making sure it’s evenly distributed and touching the ends..
Place the cut strawberries over the top.
Gently roll the dough up to form a log by taking one long side and rolling it up to meet the other side.
Using a knife, plain and unwaxed floss, or a bench scraper, cut the dough into 12 rolls (about 2” thick). Place them in the prepared 9x13 dish.
Cover with a piece of plastic wrap or a tea towel and allow to sit for 30 minutes.
Once you’re about 25 minutes into the last rise, preheat the oven to 350 degrees F (177 degrees C).
Bake at 350 degrees F (177 degrees C) for 35-40 minutes or until the tops are golden brown.
