I'm pretty sure that the Goya brand of lard is like the Armour brand of lard, not like the one you have been using. I rarely use lard so, to be on the safe side, I keep it in my refrigerator. However, according to the labeling information on the box that I have, it says that refrigeration is not required. That is why hydrogenated fats, and also partially hydrogenated fats, including those based on oils like soybean and cottonseed oil, are favored for use in commercial formulations such as those you have been experimenting with over at the Bisquick website. Those fats are quite stable and have long shelf lives.
Olive oil is generally preferred over lard in baked goods because it is low in saturated fats. For example, a tablespoon of olive oil has 14 grams of total fat, of which 2 grams are saturated fat. You can see this at http://nutritiondata.self.com/facts/fats-and-oils/509/2
. By contrast, a tablespoon of lard contains 13 grams of total fat, of which 5 grams are saturated fat. Lard also contains some cholesterol. You can see these numbers at http://nutritiondata.self.com/facts/fats-and-oils/483/2
. It is the high saturated fat content of lard that has made it so unpopular for many years. Some saturated fat is required for dietary reasons but apparently there have not been the long term studies conducted to determine how much.
The amount of lard in one or two slices of pizzas is not that great if you use normal amounts, which you would want to use anyway since too much lard may have adverse effects on the structure of the crust and maybe even its taste and mouthfeel. For example, consider the following Lehmann dough formulation below for a 16" pizza with 3.5% lard and a thickness factor of 0.105:
Morton's Kosher Salt (1.75%):
|355.2 g | 12.53 oz | 0.78 lbs|
223.78 g | 7.89 oz | 0.49 lbs
0.89 g | 0.03 oz | 0 lbs | 0.29 tsp | 0.1 tbsp
6.22 g | 0.22 oz | 0.01 lbs | 1.29 tsp | 0.43 tbsp
12.43 g | 0.44 oz | 0.03 lbs | 2.87 tsp | 0.96 tbsp
598.51 g | 21.11 oz | 1.32 lbs | TF = 0.105
As you can see from the above, the total fat for the entire pizza is 12.43 grams, or about a tablespoon. If the pizza is cut into eight slices, two slices would have a bit less than 3/4 teaspoon of total fat (and about 1.2 grams of saturated fat). One slice would be half of these numbers. If people watch their diets and don't otherwise overdo fat in their diets, eating a couple of slices of pizza using lard shouldn't be a big problem from a health standpoint. However, for some people, the mere mention of lard is enough to send them off running.
