Most of Thomas Keller’s recipes (of French laundry fame) are too complicated for my short attention span but this one is not too hard and is absolutely life changing.
8 large eggs (the fresher the better)
2/3 cup heavy cream
2/3 cup milk
1& 1/2 tbsp truffle oil
sea salt & fresh cracked pepper to taste
1 tbsp chives (finely diced)
1 oz (2-3 slices) prosciutto
1/3 c veal or chicken Stock
dash of fish Sauce (or dash of white wine vinegar)
1 tsp unsalted Butter
1/2 tsp truffle oil
A used egg carton
Prepare the egg shells
With an egg topper or serrated knife, cut off wider end of the egg (make sure cut is low enough that a spoon can fit in the opening.) If cutting with a serrated knife, lay the egg on a towel, and with a steady but gentle sawing motion, cut halfway through width of egg.
Remove knife, turn egg upright, and pop off the top of the egg. Pour 2 of the eggs into a bowl to reserve for the custard, and the others you can save for any other kitchen uses you might have for them. Reserve the paper egg carton. Reserve the shell bodies.
Under running water, using your fingers, carefully remove the membrane from inside the shell bodies. Clean up any loose shell pieces from the edges of the shell cavity, then set aside.
Prepare the Custards
Preheat oven to 275°F
In a saucepan, heat the heavy cream and milk. As soon as it reaches a boil, transfer to a blender. Carefully pulsing, slowly build speed of blender to prevent extreme splattering. While blending, add the 2 reserved eggs, truffle oil, salt and pepper to taste.
Strain the custard through a fine mesh strainer into a pitcher that pours well. Allow to sit for a few minutes, then skim foam from top of custard.
Place the shell bodies upright into a reserved egg carton (cut away extra spaces to make carton smaller.) Carefully pour custards into shells, filling about 85% full. (If pitcher is pouring like a bitch, use a funnel to help aim the pours.)
Using a pan that is a least 3 1/2 – 4″ deep, fill about 1″ of hot water into the pan. Place custards (carton and all) into the water, and top off with more water (if necessary) to have water level reach 3/4 ths up the sides of the eggs. Place pan into oven, cover with a lid or baking sheet, and bake for 40-45 minutes, or until custards are set. Remove from oven and set aside (They can stay in the warm water for about 2 hours if needed.)
Prepare the Finishing Touches and Ragout
Heat a saute pan over med-high heat, add a touch of oil, and crisp up prosciutto (just like cooking bacon.) Dab on paper towels to remove excess oils, then cut into 1/2″x 2″ pieces (there will be spare tidbits you’ll get to snack on.)
Dice the chives.
Put the stock and fish sauce into a small saucepan and bring to a boil. Simmer for about 3-4 minutes, or until it coats the back of a spoon. There should be about 3 tbsp of sauce.
Swirl the butter and truffle oil into the reduced stock. Season to taste. Place each egg in a cup, and spoon about 1 tsp of ragout on top of the custards. Add a sprinkling of diced chives, then place a prosciutto crisp in each egg.
