Rhubarb Custard Bars: A Sweet-Tart Classic
Introduction
Rhubarb Custard Bars are a nostalgic dessert that captures the essence of spring in every bite. With their vibrant tartness mellowed by silky custard and nestled in a tender base, these bars are a wonderful way to use fresh rhubarb. They’re the kind of dessert you’ll find at church potlucks, grandma’s table, or springtime brunches—beloved for both their simplicity and soul-soothing taste.
A Slice of History
Rhubarb has a rich culinary history, dating back to China over 2,000 years ago where it was first used for medicinal purposes. It wasn’t until the 18th century that rhubarb became popular in European and American kitchens as a fruit-like ingredient in pies and preserves, despite being a vegetable. Custard, with its creamy European roots, joined the tartness of rhubarb to create this perfectly balanced dessert—part pie, part bar, and all comfort.
Ingredients
Filling:
- 2 cups fresh rhubarb, chopped
