Recipe Tips For Strawberry Jam:
Purchase strawberries during their peak season for the best strawberry jam. This gives you a sweeter jam without having to add a ton of sugar. The season will vary depending on where you live, but the peak season for strawberries is typically late winter - early spring (March-May).
If your strawberries are small(typically ones from the farm are smaller), simply cut off the green tops and leave whole.
If using the Stovetop method, use a wide and tall pot to keep the hot sugar bubbles from flying out of the pan (a splatter screen comes in handy, too!). Also, make sure to keep stirring in between to prevent the sugars from burning at the bottom.
If you prefer the texture of your strawberry jam really smooth, puree it using an immersion blender.
