Tips & Variations
Selecting Rhubarb
Choose stalks that are firm and crisp, not limp. Red stalks are prettiest but green ones taste the same. Early spring rhubarb is most tender and flavorful.
Reducing Tartness
If your rhubarb is very tart, increase sugar to 1 1/4 cups. You can also let the sugared rhubarb macerate longer (up to 1 hour) to mellow the flavor.
Frozen Rhubarb
Frozen rhubarb works well but releases more liquid. Thaw and drain before using, or increase flour in the rhubarb mixture by 1 tablespoon.
Strawberry-Rhubarb Version
Replace 1 cup of rhubarb with sliced strawberries for the classic combination. Reduce sugar by 2 tablespoons since strawberries add sweetness.
Preventing Soggy Bottom
For a crispier crust, brush the bottom with beaten egg white before adding filling. You can also blind bake the crust for 10 minutes before filling.
Nebraska Farm Tradition
Many Nebraska families serve this pie with a slice of sharp cheddar cheese - "apple pie without cheese is like a kiss without a squeeze" applies to rhubarb too!
