If you're not familiar with rhubarb, it's a tart vegetable often used in desserts. You can usually find it in the produce section of your supermarket, especially in the spring and early summer.

Ingredients For Rhubarb Crisp Recipe
Rhubarb: A tart vegetable that adds a unique flavor to desserts.
Sugar: Used to sweeten the rhubarb and balance its tartness.
Flour: Helps to thicken the rhubarb mixture and is also used in the topping.
Oats: Adds a chewy texture to the crisp topping.
Brown sugar: Provides a rich, caramel-like sweetness to the topping.
Butter: Melted and mixed into the topping to create a crumbly texture.
Technique Tip for This Recipe
When preparing the rhubarb, make sure to chop it into uniform pieces to ensure even cooking. If the rhubarb is particularly tart, you can let it sit with the sugar for about 10 minutes before mixing it with the flour. This will help to draw out some of the moisture and balance the flavors. For the crumble topping, use cold butter instead of melted if you prefer a chunkier texture. Simply cut the cold butter into the oats, brown sugar, and flour mixture until it resembles coarse crumbs.
