I made a batch of lemon squares last night with my tried and true recipe that I have made multiple times. When it was done, I let it sit on the counter until completely cool and put it in the fridge.
After about 4 hours, I took it out to cut it into squares and was shocked to find it had reversed itself! The recipe has a shortbread crust on the BOTTOM and a lemon curd on TOP but when I was getting ready to cut it up, the shortbread crust was on top!
When I put it in the fridge to cool off, it was the right way, so it did this magic trick in the fridge!
There were a few changes I made to the recipe this time:
- I poured the lemon curd over the cooled crust instead of a hot crust.
- I added lemon zest to the crust for extra flavour.
- I increased the filling by 50%.
Would any of these seemingly minor changes cause this magic trick? But more important, how is it physically possible? I could see if it was different layers of a fluid cake batter that could reverse itself, but the shortbread crust is baked first so it's a solid. Not to mention it reversed in the fridge, not while baking!
It was baked in a 9 inch square pan lined with parchment paper. Does anybody want to tackle this one, so I can sleep tonight?
