Kitchen Q&A

How do I caramelize onions properly?

Cook thinly sliced onions over medium-low heat with butter and oil, stirring often for 15–18 minutes until deeply golden and soft.

What type of apple works best?

Crisp varieties like Granny Smith or Honeycrisp provide a refreshing contrast to the sweetness of the onions and richness of cheddar.

Can I use other cheeses instead of cheddar?

Yes, Gruyère or fontina can be used to give a different flavor profile while maintaining good meltability.

How to get the bread crispy without burning?

Cook sandwiches on medium heat, pressing gently, and reduce heat if the bread browns too fast to ensure even crisping and cheese melting.

Any suggested additions for extra flavor?

Adding a thin spread of Dijon mustard or a handful of baby arugula adds layers of spice and freshness.
