Here's the recipe adapted from "200 Easy Homemade Cheese Recipes" page 150.
First of all, I made a Blue du Queyras, pictured above, about 75 days in advance.
I made 2 flans at one time and doubled the recipe.
Preheat oven to 325F. Prepare a pan for 1 inch waterbath.
2 Pinch salt
10 oz. Bleu du Quayras (or another Blue cheese?)
1-1/2 tsp cornstarch
2 tbsp Creme Fraiche (oh yeah make that in advance too).
2 tbsp Cognac
Combine eggs and salt, beat with electric mixer until light and fluffy
Add cheese a little at a time, beating well (warning - not for wimpy mixers)
Beat in remaining ingredients until smooth.
Pour mixture into 10 inch pan.
Cook in waterbath for 45-50 minutes or until knife comes out clean.
Can be served warm or cold. We prefer it at room temperature.
This is amazing stuff. Bon Appetite.
