I am learning about quel/lequel

The example my teacher gave us was "Quel de ces deux plats français est le plus connu et lequel pâtisserie aimeriez-vous goûter si vous deviez visiter la France?"

However, I don't understand because I thought when choosing between a limited amount of options "lequel" is always used, so why quel at the start? Later when picking between an unlimited amount of pastries lequel is instead used. Why is this?
