Step 5

Pour the batter over the rhubarb in the pie pan. Push down any floating pieces of rhubarb so they are coated with batter.

Step 6

Bake for 45 to 50 minutes, until the top is nicely browned and evenly puffed up.

Step 7

Allow the pie to cool completely before cutting into 6 (or wedges. Serve at room temperature or chilled, with ice cream or softly whipped cream.

Step 8

The pie will keep, covered, in the refrigerator for 3 to 4 days (if it lasts that long).
