FAQs
Can I use frozen rhubarb?

What kind of apples work best?

Do I need to peel the apples?
Peeling is recommended for a softer texture, but you can leave the peels on if you prefer.
Can I make this crisp ahead of time?
Yes, assemble it up to a day ahead, refrigerate, and bake just before serving.
How do I know when the crisp is done?
The topping should be golden brown, and the fruit should be bubbling around the edges.
Can I make this gluten-free?

Can I reduce the sugar?
You can adjust the sugar to taste, but keep some to balance the tartness of the rhubarb.
Should the butter be cold for the topping?
Yes, cold butter creates a crumbly, crunchy topping.
