yes its true. i was given a cheese making kit from Lehmans. the 30 minutes mozzarella and ricotta kit was actually what i had received (not the hard cheese making kit as pictured above).
here is what the website says;
Mozzarella Cheese Kit - For authentic-tasting Italian recipes like pizza and lasagna. Includes ingredients to make Ricotta cheese. Takes 30 minutes using any kind of milk (use skim for low fat). Includes recipes booklet, cheesecloth, vegetable rennet, thermometer, citric acid, flake salt. Makes up to 15 lb.
seeing that when we tried to make cheese this summer it took days and certainly did not produce 15 lbs of cheese, this should be quite interesting. reading through the directions to appears to be similar to what we had followed except only 30 minutes.
needless to say, updates to follow.
