1. Preheat the oven to 350 degrees farenheit. 2. Peel and halve the onions, then divide each half into 4 quadrants. 3. Heat the first portion of butter in a large saucepan, then add the onions, stirring regularly. Cook over medium heat for about 30 minutes, or until tender and slightly browned. 4. Add the rosemary, then press into the bottom of a baking dish (I use a casserole dish), sprinkling with about 1/4 cup of the cheese. Leave to sit. 5. Pour the flour, baking powder and salt into a mixing bowl, and add the leftover cheese. 6. In a seperate bowl, mix together the melted butter, milk, mustard, and egg, then pour all together over the flour mixture. 7. Stir with a wooden spoon until you get a very goopy dough. Spoon the dough onto the onion mixture, making sure it covers the whole surface evenly and seals the edges. 8. Pop the whole thing into the oven for about 15 minutes, turn the heat down to about 300 degrees, then give it about another 10 minutes, checking constantly for the top to be golden and crisp looking. 9. Pull it out of the oven (the crust should test clean with a fork), and let it stand for a few minutes. 10. Cover with a large plate, then flip it over, remove the baking dish, and voilà: Savoury French Onion Pie! ---------------------------------------------------------------------------
