Put the flour, seasoned with salt and pepper, on to a large plate
Break the eggs into a shallow dish, add salt and pepper, and lightly whisk with a fork
Tip the breadcrumbs on to another large plate
Line the plates up in that order
Dip each escalope, into the flour first, then the beaten egg and finally into the breadcrumbs
Make sure both sides are well covered at each stage
Shake off any excess breadcrumbs, and transfer the escalopes to a clean plate
Heat half the butter and oil in the frying pan and, when sizzling, add two of the escalopes to the pan
Cook for 3-4 minutes on each side or until crisp and golden brown
Drain on kitchen paper
Add the remaining oil and butter to the pan
Repeat with the other two escalopes
Serve with lemon wedges.
