Notes

If you don't have the Instant Clear Jel use 3 tbsp of flour instead. 
Bars are best if chilled overnight before serving. 
Store leftover bars in an airtight container in the fridge for up to 1 week. 
Lemon bars can be frozen for up to 3-4 months. Cut the cooled bars (without confectioners' sugar topping) into squares, then place them onto a baking sheet. Freeze for 1 hour. Individually wrap each bar in plastic wrap and put it in a large bag or freezer container to freeze. Thaw in the refrigerator, then dust with confectioners' sugar before serving.
