Here is my recipe, you will need-
6 tbls unsalted butter
2 tbls peanut or olive oil
6 medium or 4 large sweet yellow onions
1 quart each chicken and beef stock
toasted French bread
3 pears, Doyenne du Comice are excellent,
but any pear good with cheese will do
Gruyere or any white cheese
a pinch of salt
1 tsp brown sugar
When done, add your stocks and simmer until about a quart has simmered away.
While it is simmering, add the remaining butter and a teaspoon brown sugar to a skillet to melt. Slice the pears thinly and add to the skillet, cooking over low heat until browned.
Line an ovenproof bowl with the pears and ladle in the onions and stock. Leave enough room in each bowl to top with a slice of toasted French bread sliced lengthwise .Sprinkle the French bread liberally with grated cheese.
Placing the bowls on a baking sheet put under the broiler until the cheese is bubbly and beginning to brown.
