Notable research has re-examined the transition between upper Mississippian and lower Pennsylvanian strata using integrated data sets that combine foraminiferal, ammonoid, and conodont evidence [1].

Bake Until Golden and Set: Bake the strata uncovered at 350°F (175°C) for 45-60 minutes, or until the top is golden and the center is set.If it’s browning too quickly, you can cover it loosely ...

Step 1. Brush a 9x13-inch baking dish with oil. Separate the chard stems from the leaves. Dice the stems and coarsely chop the leaves, keeping them separate.

As forgiving as this strata is, be sure to pull it from the oven as soon as it pulls away from the sides of the pan and has just a little jiggle at its center. And leave the crust on the bread.
