Cooking Tips
- Cut radishes evenly: Halving them ensures even roasting and better caramelization.
- Roast cut-side down: This maximizes browning and enhances flavour and texture.
- Use parchment for easy cleanup: Prevents sticking and helps with even roasting.
- Add Parmesan while hot: This allows it to melt slightly and cling to the radishes better.
- Brighten before serving: A touch of lemon zest or fresh herbs like dill or parsley adds freshness and balance to the smoky flavour.
- Don’t overcrowd the pan: Spread radishes in a single layer for better browning.
