How to Make Grandma’s Rhubarb Crisp: Step by Step

Making Grandma’s Rhubarb Crisp is a straightforward process, perfect for chefs of all skill levels. Let’s break it down:

Step 1: Prepare the Rhubarb Mixture

Start by preheating your oven to 350°F (175°C). This will ensure your crisp bakes evenly and thoroughly. Once your oven is ready, grab a large mixing bowl. Combine the rhubarb pieces, white sugar, flour, and cinnamon. Stir gently, making sure the rhubarb is well coated. This mixture will form the base of your crisp.

Step 2: Assemble the Topping

In another bowl, mix together the flour for the topping, brown sugar, rolled oats, and melted butter. Use a fork or your fingertips to blend everything together until crumbly. This mixture should resemble coarse sand when properly combined. It’s the perfect blend for a crunchy topping that complements the soft, tart rhubarb underneath.

Step 3: Layer and Bake

Take a baking dish and evenly distribute the rhubarb mixture at the bottom. Spread the crumbly topping over the rhubarb, covering it entirely. This will create a nice layer of sweetness over the tangy rhubarb. Place the dish in the oven and bake for about 35 minutes. Keep an eye on it until the top turns a lovely golden brown. This delightful aroma will fill your kitchen, making it hard to wait!

Step 4: Cool and Serve

After baking, remove the dish from the oven and let it sit for a few minutes so the juices can settle. This step is crucial; it helps the crisp hold its shape when you serve it. Enjoy it warm on its own, or consider serving it with a scoop of vanilla ice cream or a dollop of whipped cream for an extra special treat.
