Jarlsberg is a bit of a favourite with She Who Must Be Obeyed. I quite like it myself too, so I thought it was time I gave it a go. The make was derived from Scasnerkay's makes with reference also to Cheesemaking.com.
10 L Fleurieu Full Cream unhomogenised milk P=3.3%, F=3.8% brought to 32C
• ¼ teaspoon (3 dashes ) of M235 mesophilic starter ( equivalent to Flora Danica)
• ½ teaspoon (3 tads) of Propionic bacteria
• 1.75ml of 200 IMCU rennet in 35ml of water.
• 3ml of CaCl2 in 60ml of water.
Heated the milk to 95°F (35°C), then gently stirred in the cultures and covered.
Let the milk ripen for 45 minutes then added the diluted calcium chloride and stirred.
Left for a further five minutes, added the diluted rennet and stirred for two minutes.
Flocculation time = 15 min. Multiplier = 3. Coagulation time = 45 min.
Cut the curds into 2.0 cm cubes. Rest 5 min. (Probably would be better to cut the curds smaller initially rather than progressively, to achieve more control over curd size.)
Stirred the curds, progressing to stirring with a whisk, gently for 20 minutes.
Let the curds settle.
Drained one-third of the whey from the cooking pot.
Slowly, over 20 min., added 60°C water to replace about ½ the volume of whey removed, and stirred. Brought the curds to a target temperature of 39°C.
Maintained the target temperature for 40 minutes, continually stirring the curds to prevent them from matting.
Let the curds rest for five minutes at the target temperature.
Consolidated curds by hand and transferred to a lined mould.
Pressed in pot under whey with about 9lbs (~0.3 PSI) for 20 min.
Removed from pot, turned and pressed at 0.34 PSI, increased to 1.06 PSI after 10 min., for 1 hour.
Turned and pressed at 1.06 PSI for 3 hours (kept warm for the first 3 hours)
Turned and pressed at 1.06 PSI for 6 hours.
Pressed naked at 0.14 PSI for 9 hours.
Removed the cheese from the press, and currently bathing it in the brine solution for six hours.
Once it comes out of the brine, the plan is to give it 2 weeks in the cave at about 13C and 85%RH followed by a 4 week warm phase and then waxing and an indeterminate aging period.
