When life gives you lemons...

So I tried to make lemon squares from the Betty Crocker cookbook today. Kelly usually makes the lemon squares and she's done okay with this recipe. I'm not sure what I did wrong, but when I poured the filling into the crust and baked it for a second time, a thin brown crust developed over the top. It smells good and it's not burnt, but it's very hard to assess doneness. When I poked a small hole in the crust with a cake tester, I could hear the filling still bubbling underneath.

Plan B is that our neighborhood is full of bakeries.
