This is a dead simple recipe handed on from my daughter. It makes a great side dish - especially with steak, grilled chicken or most anything you wish. A big bowlful is a welcome addition to the nibbles enjoyed with a drink and goes well with mayonnaise or other dips.
1) Don't waste the onion milk - cover tightly and refrigerate, then use next day for savoury pancakes.
2) As the cooking oil is devastated, I usually use up oil that's previously cooked a couple of batches of potato fries, say. That way, I feel that I've had my monies-worth!
