For a sensible, healthy eating plan, one could do a lot worse than google "The Gascon Paradox"
Gratin Dauphinois, this dish is a favourite amongst slim elegant French ladies, and it is definitely a dish that anyone who is on a Low Carb High Fat diet and is looking to maintain their weight with a few carbs can have. Anyone who is still looking to lose weight can have this dish, dependant upon what else they may be eating that day.
There are some fiddly recipes for this dish, this is my adapted recipe which is very nice and quick and easy to make, total recipe for 2 servings;
Skin 4-6 garlic cloves, and finely slice,
Peel 220g of potato and finely slice,
Warm 250ml of Crème Fraiche so it will pour,
In a small gratin, dish layer the garlic and potato with a hint of seasoning in each layer, and cover each layer with cream, until the final layer of potato which is brushed with melted butter. Cook in a hot oven for an hour or so, until the potato is soft when pricked with a skewer. Serve with pan fried meat and green veg or just whatever you fancy.
Who said "No Potatoes" Not me.
