Bread: Sourdough or two-day-old bread

Bread thickness: 1.5cm

Butter: the outside of the bread

Cheese: top notch, grated mature cheddar

Condiment: Whichever you prefer, spread inside the bread to seal the deal

Tools: It doesn’t have to be a toasted sandwich machine- the hob is the best. Use a flat pan heated to 200 degrees Celsius.

Timing: Cook for three minutes on each side
