The Kappacasein Cheese Toastie

For one toastie

The key ingredients in the Kappacasein toastie are Poilane sourdough and Montgomery’s Cheddar.  You can buy Montgomery's Cheddar in our shops or online here, or substitute another mature, savoury cheddar. If Poilane is unavailable, substitute another sourdough bread with a close-textured crumb that will best contain the melting cheese.

Ingredients

100g of Poilane sourdough, sliced thin

100g mixed grated cheese (primarily Montgomery’s Cheddar, alongside Ogleshield, London Raclette, Comte, and Bermondsey Hard Pressed) 

Finely diced red onion 

Finely diced white onion 

Finely diced spring onion 

Finely diced leeks 

Method

Heat a grill pan or frying pan over medium-high heat. Mix grated cheese with the finely diced alliums, adjusting amounts to your taste, then assemble the sandwich. Toast in the preheated pan without adding any oil or butter, the pan should be hot enough to toast the bread and allow the oils from the cheese to come through and prevent burning. The goal is to achieve a golden brown exterior without melting the cheese too much. If the sandwich is cooked at a lower temperature for longer, the cheese will liquify too much and it will result in a less concentrated flavour. It’s a delicate balance, like so many things in life!
