🧺 Ingredients and Their Roles
A great recipe is all about understanding why each ingredient matters. Here’s what makes these bars work perfectly every time:
For the Shortbread Crust:
- All-Purpose Flour: Provides structure and crisp texture.
- Cold Butter: Ensures a tender, flaky base — cold butter prevents spreading.
- Powdered Sugar: Adds sweetness and helps the crust hold its shape.
- Salt: Balances flavor and enhances the buttery richness.
For the Custard Filling:
- Eggs: The base of any custard; they set into a smooth, creamy texture when baked.
- Granulated Sugar: Sweetens the tangy rhubarb and balances acidity.
- All-Purpose Flour: Thickens the custard to create that luscious, sliceable consistency.
- Milk or Cream: Adds creaminess; whole milk is best for a smooth texture.
- Vanilla Extract: Deepens the flavor with subtle aromatic notes.
For the Rhubarb Layer:
- Fresh Rhubarb: Choose firm, crisp stalks with vibrant color. Frozen rhubarb works too — just thaw and drain before using.
- Lemon Juice (optional): Enhances brightness and preserves the pink hue.
🥣 Step-by-Step Instructions
Step 1: Prepare the Crust
- Preheat oven to 350°F (175°C).
- In a bowl, combine flour, powdered sugar, and salt. Cut in cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
- Press evenly into a greased 9×13-inch baking dish.
- Bake for 15 minutes or until lightly golden. Let cool slightly.
💡 Pro Tip: Chilling the crust before baking helps it hold its shape and stay flaky.
Step 2: Make the Custard Filling
- In a large mixing bowl, whisk together eggs, sugar, flour, milk, and vanilla until smooth.
- Stir in the chopped rhubarb, ensuring even distribution.
- Pour the mixture over the partially baked crust.
💡 Pro Tip: Don’t overmix the custard — too much air can cause it to crack while baking.
Step 3: Bake to Perfection
- Return to the oven and bake for 40–45 minutes, or until the custard is set and no longer jiggles in the center.
- Let the bars cool completely before cutting into squares.
💡 Pro Tip: For perfectly clean slices, chill the bars in the fridge for at least 2 hours before serving.
🌸 Expert Baking Tips
- Use Fresh Rhubarb When Possible: It provides better texture and color.
- Prevent a Soggy Bottom: Blind-bake the crust for an extra 5 minutes if your rhubarb is very juicy.
- Add Depth of Flavor: Mix a teaspoon of almond extract or lemon zest into the custard for a gourmet twist.
- Make It Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free baking blend.
- Storage: Store in an airtight container in the refrigerator for up to 5 days.
