A washed-curd cheese whose holes come from propionic bacteria

Baby Swiss-style cheese is a washed-curd cheese whose eyes, or holes, form during warm ripening. Jim Wallace's Swiss Cheese recipe for New England Cheesemaking Supply (HE-B13) gives the documented four-gallon method with a two-gallon note, and the source rates it advanced.

The culture is a lactic mesophilic culture, MM100, together with Propionic Shermanii. The source calls the propionic culture essential for the holes, which is why the fermentation type is recorded as mixed. The rennet dose for the four-gallon batch is not in the text read; the two-gallon note gives 1.5 ml.

Why the whey is replaced in two steps

After the curd is cut to 3/8 inch, it rests, is stirred gently and settles, and then a third of the whey is removed. The source says this step gives baby Swiss its elastic texture. Hot water at 130 °F (54 °C) is added slowly so the curds reach 95 °F (35 °C) within five minutes, and then more is added to bring them to 102 °F (39 °C) within five to ten minutes. The total water added equals the whey removed, and the curds are stirred slowly for 30 to 40 minutes.

Pressing, rest and the acid limit

The curd is allowed to settle and consolidate, the whey is drained to about an inch above the cheese, and a plate with a weight of about half the expected curd weight is set on it. The consolidated mass is rolled in cloth and moulded. It is pressed at about twice the cheese weight, 8 to 10 lb for four gallons, turned at one-hour intervals, then increased to 20 to 25 lb, and kept at 75 to 80 °F (24 to 27 °C) for a total pressing time of five hours.

The cheese rests at 52 to 56 °F (11 to 13 °C) until the next morning. The source says it should not develop acid beyond a final pH of 5.2 to 5.3, because excess acid spoils the texture and the eye formation.

Brine, hole development and the rooms

The cheese is brined in a gallon of water with 2.25 lb of salt, a tablespoon of 30% calcium chloride solution and a teaspoon of white vinegar, for 2.5 to 3 hours per pound, with the surface re-salted halfway through. The source warns against over-salting.

Ageing takes three rooms. The cheese is kept cool at 50 to 55 °F and about 80 to 85% moisture for two to four weeks without wax, then moved to 65 to 70 °F (18 to 21 °C) and 80% moisture for three to four weeks of hole development, turned daily, with two to three weeks for smaller holes. It is finished in a cold room at 45 to 50 °F and 85% moisture for a month or more, and waxed only after the holes have fully developed.

The brewer as hot-water tank (untested adaptation)

Untested adaptation: the brewer used as a hot-water tank supplying 130 °F non-chlorinated water to a separate cheese pot or a nested one. The brewer plays no part in the development of the holes or in the ageing, which the source describes entirely in its rooms and times. This route is not the documented method above.

Method

Risks and precautions · Standard risk
Excess acid spoiling texture and eye formation

The page sets a final pH limit of 5.2-5.3 after the overnight rest.

Hazard source

Use pasteurised milk; Penn State says ultra-pasteurised and UHT milk interfere with curd formation and should not be used, and does not recommend raw milk for home cheesemaking.

Control source

Final pH after the overnight rest not below 5.2-5.3 (source quality limit)

Control source

The brewer setting is the bath temperature, not the milk temperature. Every temperature in the steps is a temperature of the milk, curd or whey, measured with a calibrated probe in the food.

The brewer configuration is a proposed adaptation that nobody has published a trial of; the source method was written for a pot in a sink of warm water or on a stove.

Use non-chlorinated water for the curd, as the page specifies.

  1. Heat the milk to 84°F (86°F for raw milk with higher fat). Add the MM100 culture (7/16 tsp for pasteurised milk, 5/16 tsp for raw), 1/8 tsp Propionic Shermanii and, if needed, 3/4 tsp calcium chloride. Ripen, covered, for 45 minutes to 1 hour. Meanwhile heat 2 gallons of non-chlorinated water to 130°F for the curd.
  2. Add the liquid rennet and let the milk set quietly for 40-45 minutes; it thickens at 10-15 minutes.
  3. Cut the curd to 3/8 inch over 5-10 minutes. Rest 5 minutes, stir gently 5 minutes, let it settle 5 minutes, then remove 1/3 of the whey; the page says this step gives baby Swiss its elastic texture.
  4. Slowly add 130°F water so the curds reach 95°F within 5 minutes, then stir for 5 minutes. Add more water so the curds reach 102°F within 5-10 minutes; the total water should equal the whey removed. Stir slowly for 30-40 minutes.
  5. Let the curd settle and consolidate, drain whey to about 1 inch above the cheese, and set a plate on it with a weight of about half the expected curd weight (2.5 lb for 4 gallons). Roll the consolidated mass in cloth and put it in the mould.
  6. Press at about twice the cheese weight (8-10 lb for 4 gallons), turning at 1-hour intervals, then increase to 20-25 lb; keep the cheese at 75-80°F for a total pressing time of 5 hours.
  7. Rest the cheese at 52-56°F until the next morning (8-10 hours). The page says it should not develop acid beyond a final pH of 5.2-5.3.
  8. Brine in 1 gallon water with 2.25 lb salt, 1 tbsp calcium chloride (30%) and 1 tsp white vinegar, for 2.5-3 hours per lb, re-salting the surface halfway. Do not over-salt.
  9. Age cool at 50-55°F and about 80-85% moisture for 2-4 weeks, without wax.
  10. Move to 65-70°F and 80% moisture for 3-4 weeks of hole development (2-3 weeks for smaller holes), turning daily.
  11. Finish in a cold room at 45-50°F and 85% moisture for a month or more. Wax only after the holes have fully developed.
