Equipment

  • Jar or Small Bowl (for pickled onions)
  • Sharp Knife & Chopping Board
  • Cheese Grater
  • Non-Stick Pan & Spatula/Turner

Ingredients

Pickled Onions

  • 1 cup / 240ml Red Wine Vinegar
  • 1 medium Red Onion, very finely sliced
  • 1 tbsp Sugar
  • 1 tsp Salt

Sandwich

  • 8 small-medium slices of Bread (here I use Sourdough)
  • 4 square slices of Cheddar
  • 5oz / 150g Gruyere, grated (see notes)
  • Butter, as needed

Instructions

  • Pickled Onions: In a jar or small bowl combine vinegar with salt and sugar. Add in finely sliced onion, give it a shake/mix then leave to pickle for at least an hour, or until they begin to wilt and turn pink.
  • Prep Sandwich: Spread one side of each of your slices of bread with butter. Place two of them butter-side-down in a non-stick pan with the heat OFF. Top with cheddar, followed by pickled onions, then grated gruyere. Top with a second slice of bread butter-side-up.
  • Cook Sandwich: Turn heat to a medium and fry both sides until golden, with the cheese nice and gooey. Prep the other two sandwiches to one side as these cook. Serve up and enjoy!

Notes

a) Pickled Onions - If you don't have red wine vinegar then the next best option is apple cider vinegar. Make sure you either drain them or shake off excess liquid before you add them to the sandwich, otherwise it'll turn soggy as it fries.
b) Gruyere - This adds a gorgeous nutty flavour to the sandwich. Most cheese goes beautifully with pickled onions though if you don't have gruyere (Swiss, Gouda, Emmental etc). Failing that just add more cheddar.
c) Calories - Per sandwich assuming 2 tsp butter for each sandwich:
