Lightly crush the garlic cloves and cut them into thick slices (1/8th inch). Set aside
Slice the peppers into 1/4 inch rounds.
Remove the root from the scallions and cut them into 1.5 inch lengths. The green and white parts can be used.
Heat the oil in a large work or pot to 350F over medium-high heat. Don't fill the cooking vessel more than halfway or you may have a boil-over which can be very dangerous.
When the oil reaches 350F, carefully scatter the pieces of battered cuttlefish into the oil so that they do not clump together. Immediately stir the cuttlefish once it is in the oil to separate any pieces that may have stuck together.
Allow the cuttlefish to fry for about 2-3 minutes at 350F.
Use a strainer or slotted spoon to lift the cuttlefish from the hot oil. Set it aside in the strainer or on a plate and let it rest for 2-3 minutes. Keep oil at 350F while cuttlefish is resting
After cuttlefish has rested, the steam inside the cuttlefish will have slightly softened the crust. Place the cuttlefish back in the hot oil for another minute to crisp it back up.
Remove the cuttlefish from the oil and set aside in the strainer or on a plate lined with paper towels.
If you were using a wok, empty out the oil and clean the wok. If you were frying in a pot, set it aside and grab a large saute pan.
Heat the wok or sautee pan over high heat and add 2 tbsp of cooking oil. When the oil is smoking, add the sliced garlic and immediately follow it with the sliced chilies. Stir fry for about 10 seconds.
Add the scallions and stir fry for about 15 more seconds. All the vegetables should have some light browning but not be burnt.
Add the cuttlefish to the pan and stir fry everything together over high heat for 20-30 seconds.
While you are stir-frying, sprinkle on 1 Tbsp of the salt and pepper mix that you made earlier.
After stir-frying for 20-30 seconds, turn off the heat and taste a piece of cuttlefish. It should be pleasantly salty. If it needs more seasoning, add more salt and pepper mix.
Plate and enjoy.
