Notes
Tips and Substitutions
Always wash and trim the radishes. I cut the root end off and make sure the top stalk is trimmed off as well. Once washed, pat the radishes dry.
Cut the bigger radishes in half or quarters and leave the smaller ones uncut. Tryin to keep the radishes all similar in size before oven roasting them.
Substitute the umami seasoning for 1 teaspoon salt, ½ teaspoon pepper, and ½ teaspoon smoked paprika.
Depending on the umami seasoning you use, you may need a little salt and pepper.
