Using frozen strawberries without thawing: Always thaw and drain excess water from frozen strawberries for the best texture.
Overboiling the mixture: Do not boil for too long; keep it under a minute to maintain the thickening ability of cornstarch.
Not adjusting sugar levels: Taste your mixture; sugar levels can vary based on strawberry sweetness, so adjust as needed.

Ignoring consistency checks: The filling should coat a spatula heavily. If it’s too thin, simmer it longer until thickened.
