We sliced. Mark (the younger one, not the father one) and Alex were actually quite good helpers.
We speared and skinned. (We gutted too - but I'll spare you that photographic image.)
Then we marinated - in olive oil, red wine vinegar, lots of garlic, salt and pepper, and bay leaves. (This is not a traditional Maori recipe, needless to say - they most often smoke the eel whole, no skinning required. I should have thought of that -- but then I don't have a smoker.) And then we grilled - or barbecued as the Kiwis would say. It was really quite delicious and I recommend the basic but very good marinade above for any substantial white-fleshed fish you plan to grill. I don't, however, recommend skinning and gutting your own eel.
