Reuben Sandwich

👨‍🍳 Method

1. 1
   Spread the butter on the outside of slice the bread.

   💡The butter goes on the outside, the side that meets the pan: it's what gives the bread its golden, crisp crust.
2. 2
   Mix the mayonnaise and tomato paste into a sauce and spread it on the inside of slice the bread.
3. 3
   Place the yellow cheese, meat and sauerkraut on half of slice the bread and cover each one with another slice, buttered side out.
4. 4
   Heat a heavy pan over medium heat.

5. 5
   Grill the sandwiches 3 minutes per side, until the bread is golden and crisp and the cheese has melted completely.

   💡Medium heat, not high: the bread browns at the same pace the cheese melts, while over high heat it burns outside before the cheese inside melts.
