Place potatoes on baking sheet, sprinkle with more sea salt and bake for 1 hour or until soft when pierced. Note: the internal temperature of a fully cooked potato is 210 degrees F.
Split the hot potatoes in half lengthwise, squeeze open (you can use oven mitts if too hot to handle) and place on a plate.
Garnish potato in this order – 1 T onion, 2 tsp mint, ½ lemon; hand squeezed and ¼ cup olive oil.
