This amazing sandwich is more than that, it's culture; it awakens the gourmand in you.
Ingredients: fresh sausage, smoked sausage, steak, baloney, cheese, bread and spicy sauce. Some will came with a fried egg.
There's a couple of rules you should follow to find the best Francesinha: 1. The quality of the ingredients; 2. The kind of bread and cheese that is used; 3. Fresh French fries (they shouldn't be frozen ones); 4. The sauce balance - it should be spicy and light, and you shouldn't identify the ingredients that are used.
This said, the one in Golfinho has it all and perfectly balanced. I've tried a lot in Porto and this is the best, I can guarantee it!
