Common Questions About Cooking

→ How do I get my onions perfectly caramelized?

Cook them low and slow, about 15-20 minutes, stirring occasionally. Don't rush the process - this develops their sweet flavor. If they start to stick, add a small splash of water.

→ Can I prepare the sauce ahead of time?

Yes, the secret sauce can be made up to 3 days ahead and stored in the fridge. It actually tastes better after the flavors have time to blend together.

→ Why use two types of cheese?

Swiss cheese offers a nutty flavor and smooth melt, while cheddar adds sharpness and color. Together they create the perfect balance of flavors and texture.

→ How thin should I make the patties?

Make them thinner than regular burgers since they'll be sandwiched between bread. Aim for about 1/4 inch thick and slightly larger than your bread, as they'll shrink while cooking.

→ What's the best way to prevent the bread from burning?

Use medium heat and watch carefully. The key is to let the cheese start melting before flipping, which usually takes 2-3 minutes per side.
