I'll be serving 4 burgers (medium rare, toasted buns, choice of cheese, onions, lettuce, etc.) with fries. I can use the oven to keep some of these things warm and crisp, how should I go about it? What sequence, what temp? Thank you!
My instinct is that you should have everything cook at the same time. Cut all veggies and make sure fries are pre cooked so the second frying is for exterior crispness. You should be able to drop fries while burgers are cooking. I would put burger down, drop fries, flip burger, pull fries, toast bun and then plate everything. Working to your ability.
