Butter-Poached Lobster Tails
This was a first for me... but I will make lobster this way again, I guarantee. This was just too amazing. Tender and sexy. Delicious. Try it... you'll love it.
1 lobster tail, per person, shells removed.
Non-salted butter, cut into small chunks
1 tablespoon water
Determine how much butter you will need by placing the lobster tails in a large enough pan, side by side; add just enough water to cover. Immediately remove the lobster tails, drain them, set aside; and measure the water in the pan. You will need this amount of butter to cover and poach the tails.
When you are about an hour from serving the lobster tails, take them out of the refrigerator and bring them to room temperature.
To make the Beurre Monte:
Definition of Beurre Monte: Butter is an emulsification of 80% milk fat, 18% water, and 2% milk solids. Heating butter above 160 degrees will cause it to "break" or separate into its different composition parts. A Beuree Monte is a techniques of keeping melted butter in an emulsified state between 180 degrees and 190 degrees, which is sufficient to poach meats or vegetables.
In a saucepan, bring the 1 tablespoon of water to a boil over high heat; reduce the heat to low and begin adding the chunks of butter (a little at a time) whisking to emulsify. Once the emulsion is started, more butter may be whisked in faster. Hold the temperature of the Beurre Monte between 160 and 190 degrees for poaching. DO NOT BOIL OR THE MIXTURE WILL BREAK! The mixture should have the consistency of a very thick butter sauce. NOTE: Beurre Monte can be set aside on the stove after being prepared. You should use the beurre monte within an hour after you make it.
When ready to poach the lobster tails, use a thermometer and bring the beurre monte up to at least 160° degrees, but not over 190° degrees. Depending on how large and how many lobster tails you are preparing, will determine how long to poach them; it usually takes from 5 to 7 minutes. They should not be rubbery but of a soft consistency (almost as if not completely cooked). The lobster should be white and not very opaque in color. When done, remove them from the Beaurre Monte and serve.
