The idea is to press only what you need as you need it. We will raise black oilseed sunflower which stores well in the hull. Run the whole seed hull and all through a food processor heat to about 170 degrees and press. Pressing is done with a homemade press using a 3 to 4 ton hydraulic jack.
We are pretty much vegetarians though we do eat a little meat once in a while so we don`t have access to larding. We do use a little olive oil but the good stuff is pretty expensive.
"Modern diets can contain as much as 30% of calories as polyunsaturated oils, but scientific research indicates that this amount is far too high. The best evidence indicates that our intake of polyunsaturates should not be much greater than 4% of the caloric total, in approximate proportions of 1 1/2 % omega-3 linolenic acid and 2 1/2 % omega-6 linoleic acid.30 EFA consumption in this range is found in native populations in temperate and tropical regions whose intake of polyunsaturated oils comes from the small amounts found in legumes, grains, nuts, green vegetables, fish, olive oil and animal fats but not from commercial vegetable oils. "
"Problems associated with an excess of polyunsaturates are exacerbated by the fact that most polyunsaturates in commercial vegetable oils are in the form of double unsaturated omega-6 linoleic acid, with very little of vital triple unsaturated omega-3 linolenic acid. Recent research has revealed that too much omega-6 in the diet creates an imbalance that can interfere with production of important prostaglandins.34 This disruption can result in increased tendency to form blood clots, inflammation, high blood pressure, irritation of the digestive tract, depressed immune function, sterility, cell proliferation, cancer and weight gain.35" http://www.westonaprice.org/knowyourfats/skinny.html#poly
Since you are vegetarians (not vegans, correct?), I would focus on butter and use the fresh pressed sunflower oil occasionally. Butter is cheap right now and I am stocking up. It freezes very well.
Thanks for the heads up on the oils wifezillah. My problem with butter is that unless you are buying organic it still contains RBGH as well as all the other who knows what of commercial dairy products. I am all for true organics but a lot of that stuff is to expensive for our situation.
I am trying to find a source of raw organic affordable milk in our area to be able to make our own butter, cheese and so on.
Wifezilla, riddle me this - when I deep fat fry center cut bacon in peanut oil for some odd reason the house gets smokey right after I throw in a pound of unsalted butter.
I save my bacon fat and chicken fat for frying.--also use butter and sometimes olive oil. The only other grease thing I have in my house is lard, but I haven't made that myself yet.
The smoke point on unsalted butter is lower than that of peanut oil. If you want to stop that smoke, you have to clarify the butter to remove the non-fat milk solids from the butter.
Now I figure you are being a smart aleck with that question (unless there is some mysterious reason you fry your butter ), but smoke point is something people don't know much about. There is a handy chart here... http://whatscookingamerica.net/Information/CookingOilTypes.htm
You don't want to heat oils past that smoke point. Besides messing up your food and making your house stink, it turns the oil from a healthy source of fatty acids in to toxic sludge.
