1. Cut radishes into same sizes. I normally halve the regular ones and quarter the larger ones. Keeping them of the same size helps in cooking them uniformly. 2. Just a basic spice rub works well along with some olive oil. You can skip oil and manage without it if you are looking for a zero-oil version. Lemon juice and a little water will help the spices adhere to the radishes. 3. You can add some grated cheese for more crunch and flavour. Use vegan cheese for dairy free. 4.You can also add 1 tbsp. cornflour in case you want crunchy bits on your radishes. 5. This recipe is vegan as is and is also gluten free. 6. Shake the basket during cooking time to ensure even cooking. 7. You can use your favourite rubs or spice mixes here like Cajun seasoning, taco or fajita seasoning etc.
