Lemon pie filling might not thicken if the ratio of cornstarch or flour to liquid is off, or if it hasn't been cooked long enough. Ensure you're cooking it until the mixture bubbles and thickens. Using fresh lemon juice can also impact consistency, so consider adding a bit more cornstarch. Stirring constantly to avoid lumps is crucial too. If it still doesn't thicken, letting it cool in the fridge can sometimes help set the filling.

FAQs & Answers

  1. How much cornstarch should I use to thicken lemon pie filling? Typically, use about 2 tablespoons of cornstarch per cup of liquid for a firm lemon pie filling. Adjust slightly depending on juiciness and desired thickness.
  2. Can I use flour instead of cornstarch to thicken lemon pie filling? Yes, flour can be used but requires cooking longer to remove the raw taste. Cornstarch usually yields a clearer and smoother filling.
  3. Why does my lemon pie filling become runny after cooling? Runny filling can result from insufficient cooking time or too little thickener. Cooling can also affect setting, so ensure proper ratios and cooking until bubbling.
  4. How can I avoid lumps when thickening lemon pie filling? Stir the filling constantly while cooking and gradually add the thickener mixed with a small amount of cold liquid to prevent lumps.
