Bring a pot of water to a boil and add nuts. Boil for exactly one minute.
1 cup raw almonds, 4 cups water
Drain the almonds in a colander or strainer and immediately run under cold water. This will cause their skins to loosen and become somewhat wrinkled.
Use your fingers to squeeze individual almonds, which will cause the skin to pop right off. Or your hands to squeeze handfuls of almonds at once. This presses the nuts against each other and finishes the job more quickly. Remove skins and sort out the skinned almonds as you go.
Pat the almonds dry and use immediately or store in an airtight container for up to one month. For longer storage, freeze for three months.
Notes
You can use any quantity you like; just be sure that the water if sufficient to completely cover the nuts.
The almonds will sink in the boiling water, but by the end of 60 seconds, they will begin to float.
