Sugar and Salt in Food Preservation

Wednesday, July 8th, 2009

by Catherine Haug

During our discussion of topics for our upcoming event, Putting Food By Without Refrigeration, the question of salt was raised,

Salt is needed for so many of these processes; what will we do when we can no longer import salt from out of the area?

I ask our ESP community:  Are there any salt licks or other natural sources of salt in our valley?

And it’s not just salt, but also sugar that is used in preservation of foods; here are just a few uses: (more…)

Making Cheese & Tofu, March 25, 2009

Saturday, March 28th, 2009

Presentations by Fran Wade and Steve Eisenberg, ESPers during break at cheese & tofu gathering

Updated 11/8/09; see ‘When using pasteurized milk’ below.

We had an excellent and enthusiastic turnout for this gathering; thank you ESPers! To stimulate our taste buds, Fran brought goat cheese samples from Gayle Prunhuber, and Steve brought a sample batch of his homemade soy milk.

Both Fran and Steve provided instructional handouts, which are available on our website. See ESP Fermentation & Culturing Files for:

  • Cheese and Tofu Making, by Fran Wade; includes basic instructions, and recipes for a semi-hard cheese (mozzarella-like), cream cheese, ricotta, tofu and soy burgers.
  • Soya Milk & Tofu (Using SoyaJoy Machine), by Steve Eisenberg: includes basic instructions, and recipes for soy milk, tofu and soy burgers.

See Gathering Summary: Making Cheese & Tofu for complete summary of the gathering, including excellent tips that came up during the presentations, sources of equipment and supplies, and list of resources.

See also: Cheese Making for Beginners, by David B. Fankhauser, Ph.D.; University of Cincinnati Clermont College  for excellent information and a tutorial sequence.

When using pasteurized milk

Subsequent to the gathering, we learned how to treat pasteurized milk so that it will form a curd. [Pasteurization denatures the protein that binds calcium so that the milk will not form curds]. Add 1/2 tsp of a 30% Calcium Chloride solution per gallon of milk BEFORE adding rennet. This added calcium helps to restore the altered protein so that the curds can form.

You can obtain the 30% CaCl2 solution at Evergreen Pharmacy, or any compounding pharmacy. Or order it from the web.

See Journal of Dairy Science article: “Concerning the Addition of Calcium Choride to Milk for Cheese Making,” by W. V. Price, Department of Dairy Industry, Cornell University, for the science. (http://jds.fass.org/cgi/reprint/10/5/373.pdf)
