FAQ

Can I use regular sugar instead of erythritol?

Yes, but it won't be low-carb anymore. Use 1 tablespoon regular sugar for similar sweetness, though it will add carbohydrates to the dish.

How do I know when the radishes are done?

They should be tender when pierced with a fork and have golden-brown caramelized edges. The texture should be similar to roasted potatoes.

Can I freeze roasted radishes?

Not recommended as radishes become mushy when frozen and thawed. They're best enjoyed fresh or refrigerated for a few days.
