VERY IMPORTANT: You do not add the honey to the Mash or the boil. Instead, mix 4 lbs of honey with sterilized water around 95 deg F (35 deg C) in a sterilized Jug or large jar. Cap the jar/jug and shake vigorously until the honey is integrated completely with the water.
When you are chilling the wort and you hit about 95 deg f, pitch then honey/water mixture (In meadmaking, this is called 'the must') into the wort. Before transfering to the fermenter, ensure that you stir the wort well to integrate the must.
Why? Nutritional and flavor compounds start to deteriorate at higher temps. Honey is abiotic and usually will not negatively affect sterilized wort. At high enough temps, honey caramelizes and looses almost all of the delicate honey flavors and nutritional benefits.
Version 1.2: This version uses Kveik (Imperial yeast Kveiking) as the yeast type. It's completely untested. For a more standard option, use Belgian or Scottish ale yeast. I have previously made this with Wyeast 1728 or Imperial yeast "Tartan".
