This one came out really good! It's kind of a happy medium between the other two! Just slightly less crispy than the mayo, but not nearly as oily as the ghee, but still very savory and flavorful!
My final verdict is that specifically in an air fryer salted butter is king!
Runner ups are mayo for best texture, and ghee for most intense flavor, but butter is the total package lol
If anyone wants to recreate any of these I used Duke's mayonnaise, 4th & Heart unsalted ghee butter, and Minerva sea salt salted butter
The bread was Publix bakery round sourdough
The cheese was Publix swiss and Publix sharp cheddar pre sliced
All three sandwiches were made in an air fryer set to 370F for 8 minutes flipped halfway through, then another 2 minutes at 400F for extra crispiness
I hope to see all of your sandwiches here soon!
