Heat oil on high heat and, when hot, reduce the heat to low and drop the shallots in, stirring constantly with a wooden spoon or chopsticks.
When they’ve turned a golden colour, dish out with a slotted spoon and drain on a plate lined with kitchen towel. They will continue to brown as they cool down.
When cool, store in an airtight container in the fridge.
Drain the used oil into a sterilised jar, leaving the last bit, as that will be full of sediments. Store at room temperature.
