Common Mistakes to Avoid
When making Old-Fashioned Rhubarb Crumble, it’s easy to overlook a few key details. Here are some common mistakes to avoid for the best results.
- Using Too Much Sugar: While rhubarb is tart, adding excessive sugar can overpower its natural flavor. Stick to the recommended amount to maintain balance.
- Not Prepping the Rhubarb Properly: Always wash and cut rhubarb into even pieces. Uneven sizes can lead to inconsistent cooking and texture in your crumble.
- Skipping the Cooling Time: Allowing the crumble to cool before serving helps it set properly. If you serve it too soon, the filling may be too runny.
- Overmixing the Crumble Topping: Mixing too vigorously can lead to a tough topping. Combine ingredients just until crumbly for that perfect texture.
- Ignoring Oven Temperature: Ensure your oven is preheated correctly. An oven that’s too hot or too cold can affect baking time and results.
