• Poached Eggs

    Posted by PolyScience Staff

    Cooking Time: 45-60 minutes

    Ingredients:
    Large hen eggs – quantity is variable

     

    Step 1:
    Set the rear pump flow switch to fully closed. Set the front flow switch to the minimum flow to ensure the delicate proteins in the whites do not separate from agitation. Set the temperature of the Sous Vide Professional™ to 64°C / 147.2°F.

    Step 2:
    Once target temperature is reached, gently place eggs in circulating water bath. Use a ladle or slotted spoon to gently lower the eggs so they do not crack.

    Step 3:
    Cook to desired doneness for 45 minutes. Do not hold at temperature for more than 120 minutes.

    Step 4:
    If plating immediately, gently crack egg onto a paper towel to capture any excess liquid. Gently, roll the egg off of the towel onto a plate.

    If serving at a later point, do not crack. Plunge egg into ice bath. Store up to 48 hours under refrigeration. Reheat egg by placing in 60°C / 140°F circulating bath or placing egg into a pot of simmering water for 60 seconds.

  • Sous Vide Techniques: Entire Meals

    Posted by PolyScience Staff

    Can you cook an entire meal at the same time in a Sous Vide™ Professional?
    Yes. There are different ways of doing this – with different temperatures or not.

    For foods that you’d like to cook at different temperatures, you have 2 options:

    Staged approach – stage it, hold it, finish it, serve it
    Since food doesn’t overcook when holding at a lower temperature, one simply organizes the sequence from high to low temperatures. For example, first cook carrots and potatoes at 185°F/85°F for 45 minutes, then lower the temperature to 138°F/59°C for medium-rare beef tenderloin. Adding ice cubes helps to speed up the cool-down process.

    The cook-chill-reheat approach
    Pre-cook different foods, chill in an ice-bath and store in the refrigerator. Later re-heat all foods at the temperature that you’ve used for the food with the lowest temperature, which would be at 138°F/59°C for example when serving medium-rare meats. Note: an ice bath is the most efficient and safest way to chill down a vacuum sealed pouch of food. Do not put it in the refrigerator to chill down, because it can take days and warms up the rest of your fridge content.

    If you like to cook food at the same temperature, but don’t want to lose the other benefits of sous vide:

    Slow Cooker concept – one-pot meals and stews
    A Sous Vide™ Professional can be used like a slow cooker. Simply vacuum seal your stew into a bag or fill into a container that sits in the water bath and will be cooked by the surrounding temperature-controlled liquid.

  • Crème Anglaise

    Posted by PolyScience Staff

     

    Makes approximately 20 lollipops or 2 servings of Crème Anglaise

    Ingredients:
    5 egg yolks
    1 cup milk
    1 cup heavy cream
    3/8 cup sugar
    1 vanilla bean, split, seeds scraped, and seeds and pod reserved
    Pinch of salt

    For more information on food safety, please click here.

    Step 1:
    Set the Sous Vide Professional™ to 179°F / 82°C, with the rear pump flow switch closed and the front flow switch set to fully open. Make sure your cooking tank has approximately a 3-gallon capacity and is covered.

    Step 2:
    In a blender, combine the egg yolks, milk, cream, sugar, vanilla bean seeds and salt (do not blend the vanilla pods). Blend on high speed for 15 to 30 seconds (this breaks up the chalazae on the egg yolks so you don’t need to strain the finished sauce).

    Step 3:
    Pour the mixture into a vacuum bag, add the vanilla bean pod and vacuum seal the bag, removing as much air as you can.

    Step 4:
    Once the target temperature of 179°F / 82°C is reached, place the bag in the circulating water bath.

    Step 5:
    Cook for 15 to 20 minutes. Crème anglaise cooked for 15 minutes will be thin and will just coat a spoon; it will be thicker if cooked for 20 minutes. Avoid cooking longer than 25 minutes, as the crème anglaise can take on an “eggy” aroma, although it will not curdle.

    Step 6:
    Remove the bag from the circulating water, wrap it in a kitchen towel and massage it for 2 to 3 minutes. If you omit this step, the crème anglaise will look lumpy. Place the bag in a cold water or ice bath to chill. For best results refrigerate overnight. Serve the crème anglaise with fresh fruit or freeze on the Anti-Griddle™.

    Step 7: Optional
    Prepare your Anti-Griddle™ by spraying a thin coat of olive oil or cooking spray onto the stainless cooktop. Wipe spray evenly with paper towel. Turn Anti-Griddle™ on.

    Step 8: Optional
    When Anti-Griddle™ surface has reached it’s coldest point, pipe or spoon crème anglaise onto the cooktop. Place a paper lollipop stick halfway across dollop. Allow bottow to freeze before attempting to flip, using a small, stainless offset spatula. Flip, if desired.
