Slice the courgettes into thin sticks smaller than your finger.
Put in a sieve over the sink and sprinkle lightly with salt. Leave for 10 minutes to drain off the excess liquid.
While they sit, get a fryer on to 160°C.
Get two bowls ready, one with a splash of milk and another with a few shakes of flour (you won't need much).
Rinse off the salt, then bathe them in milk. Transfer to the flour then fry for 3 minutes until golden brown. Salt and serve immediately.
