Common Recipe Questions
- → How can I caramelize onions perfectly?
Keep your heat low and stir them every few minutes. It takes about 15-20 minutes to bring out their sweetness. If the pan gets sticky, add a drop of water to loosen it.
- → Can I make the sauce before cooking?
Absolutely! Mix it up to 3 days ahead and store it in the fridge. The flavors get better the longer they sit together.
- → Why mix two cheeses for this sandwich?
Swiss melts smoothly with a touch of nuttiness, while cheddar brings a pleasantly sharp kick. Together, they’re the best combination for flavor and texture.
- → How thin should the patties be?
Keep the patties thin—about 1/4 inch. Make them wider than your bread since they'll shrink a little while cooking.
- → How do I stop the bread from burning?
Cook over medium heat, and be patient. Wait until the cheese softens before flipping, usually 2-3 minutes per side.
