i use the hinge screwed in cut round with a sharp knife
then chisel
as an aside some cheap hinges dont have enough gap so if you sink both leaves in the door and frame will almost touch so surface mounting one leaf is the only easy way
If doing them in quantity then router and jig (Trend). For one-offs and rehangs (new door in existing casing) then chisel. I'm old fashioned enough to use a butt marking gauge as well
