Good to know
Tips
- Toasting the bread first stops the cheese soaking in and keeps the base crisp.
Common mistakes
- Melting the cheese over direct heat, which makes it stringy and greasy — stir it in off the heat.
Storage
- The cheese mixture keeps 3 days in the fridge.
Variations
- Buck rarebit: Topped with a poached egg.
