- If you prefer a less sweet dessert, reduce the sugar by a couple of tablespoons.
- Try substituting mini marshmallows with chopped dried fruit for a different texture.

FAQs
Can I make this dessert ahead of time?
Yes, it’s actually recommended to chill the fluff for at least 2 hours to let the flavors meld and the texture set. You can prepare it up to a day in advance.
Can I use regular marshmallows instead of mini marshmallows?
You can, but mini marshmallows distribute more evenly and melt better into the mixture. If using regular marshmallows, chop them into smaller pieces before folding in.

- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract

Instructions
- Cook Rhubarb Compote: In a medium saucepan, combine the chopped rhubarb, granulated sugar, cornstarch, and water over medium heat. Stir occasionally as you cook until the mixture thickens and the rhubarb becomes tender, about 8 to 10 minutes.

Notes
