Can I make this sandwich without apple butter?
Yes. Substitute apple butter with fig jam, cranberry sauce, or honey mustard for a different but equally delicious flavor profile.
What cheese works best in this melt?
Muenster is ideal because it melts smoothly and has a mild, creamy flavor. Brie, Swiss, or smoked gouda are solid alternatives.
Should I butter the bread before grilling?
Yes. Lightly butter the outside of the sourdough slices to achieve a golden, crispy crust and even browning.
Can I make this ahead?
Assemble the sandwich without grilling up to 2 hours ahead; keep it wrapped to prevent sogginess. Grill just before serving.
What's the best way to grill this sandwich evenly?
Use medium heat and press gently with a spatula for 2-3 minutes per side until the cheese melts and bread is golden. Don't use high heat or the outside will burn before cheese melts.
