Typical costs: Having a contractor level and prepare the area then pour a concrete slab ranges from $1,000-$2,000 for a 10x20-feet; $4,000-$6,000 for 80x20-feet; and $5,000-$10,000 for 100x100-feet. Smaller projects cost more per square yard because of minimum travel, labor and equipment costs.
What makes yogurt - well, yogurt? The words live and active cultures refer to the living organisms, Lactobacillus bulgaricus and Streptococcus thermophilus, which convert pasteurized milk to yogurt during fermentation. Note that the milk is pasteurized before culturing to remove any harmful bacteria.
The yogurt culture includes all the strains of bacteria in the product and makes up about 1% of the ingredients. Frozen yogurt is made in much the same way as ice cream and, with the exception of yogurt culture, they are made from similar ingredients. Two of the most important elements in frozen yogurt are water and air. Air is incorporated into the mixture to add volume.
