Cass, I have some of DH's grandmothers recipes books here ATM and there is a recipe for a "Rhubarb Fool", sounds like a quick and easy dessert. The measures are all quite old, but it has a conversion table.

Rhubarb Fool
1/2 pint stewed rhubarb
1 gill cream
1 gill boiled custard

1/2 pint = 1 cup; 1 gill = 1/2 cup

Put rhubarb through a seive, stir in the custard, then lightly whipped cream. Serve in chilled tall glasses and decorate with marachino cherries or seeded grapes.
