    Elderflower Smoked Griddled Halloumi – by Chef Eddie Shepherd
    300g Halloumi
    Dried Elderflower

    Heat a griddle pan to a medium high heat.

    Slice the Halloumi into centimetre thick pieces. Cook the Halloumi for about a minute on each side (giving it a half turn while cooking each side to get a criss cross pattern if you like)

    Once cooked set the Halloumi slices to one side to cool.

    Trim the cooked Halloumi to even squares and place into a glass bowl.

    Cover the bowl with cling film and smoke using the Polyscience Smoking Gun, loaded with dried elderflower, filling the covered bowl with smoke. Sit covered for around five minutes to allow the Halloumi to take on the flavour of the elderflower smoke.

    8 2 oz Slices Spiral Cut Ham
    16 oz Arrowleaf Spinach (wilted with EVOO and diced shallot)
    iSi Hollandaise Sauce (See recipe below)
    4 Toasted fork-split English Muffins

    Poached Eggs 64°C / 147.2°F for 60-75 minutes
    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 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.

    Sauce Hollandaise
    Ingredients for a 0.5L / 1 US Pint iSi Whipper:
    300 ml Clarified Butter, warmed to 60°C / 140°F
    100 ml White Wine Reduction (200ml, reduced by half, infused with 1 Thyme Sprig)
    4 Egg Yolks
    1 Egg

    To Taste:
    Kosher Salt
    White Pepper, finely ground
    Lemon Juice, fresh squeezed
    Green Tabasco

    Step 1:
    Whisk the white wine reduction with the egg and egg yolks.

    Step 2:
    Add the warmed clarified butter to the egg and wine mixture.

    Step 3:
    Season to taste.

    Step 4:
    Pass mixture through iSi Funnel + Sieve into the 0.5L / 1 US Pint iSi Whipper. Screw on 1 iSi Cream Charger and shake vigorously.
    Keep warm in a water bath or a bain-marie at temperatures of up to 65°C / 150°F.

    This sauce does not have to be whisked over simmering water.
    It can be kept warm and easily reheated in the iSi Gourmet Whip PLUS in a water bath or in the bain-marie without coagulating at temperatures of up to 65°C / 150°F.

    For preparations in the 1L iSi Whipper double the amount of ingredients. Screw on 2 iSi Cream Charges and shake vigorously after each one.

    Instructions for Smoked Butter:
