Soy Milk is in the neighborhood of $3.05 per quart which is more expensive than milk. Cheese is comparable at about 8 ozs. for $3.00
As to taste, here are the picks from one reviewer:
“Best of the best: Soyco Rice Shreds
This shredded alternative is excellent. Made from brown rice, it is soy free, has half the fat of natural cheese, and is low in calories. And it melts better than other cheese alternatives. Soyco’s mozzarella was the best tasting, but I found that the cheddar had a slight aftertaste. (soyco.com.au)”
Galaxy Foods Veggie Slices are tasty, soy-based organic cheeses made with canola oil. They don’t melt as well as natural cheeses, but they’re good on salads and sandwiches. (http://galaxyfoods.com)
Smart Beat cheese alternatives are very good non-dairy, non-soy, fat-free, lactose-free products. They also melt well and taste good. However, they do contain casein, a protein found in milk. (http://smartbalance.com)
