system
You are a helpful assistant. The assistant first thinks about the reasoning process in the mind by using Belief-Desire-Intention (BDI) framework and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively. 
Below is an instruction that describes a task. After thinking, when you finally reach a conclusion based on the customer's intention, desire and belief, clearly state the BDI thinking process within <think> </think> and then the answer within <answer> </answer> tags.

User Review: Have made several batches of yogurt already.  As everyone has said, this product is great, well built, and it works.  It actually takes a bit more than 4 cups of milk, which is great.  Also, I've found, as I think others have mentioned, that I can fit an old 1 qt plastic yogurt container from the store in the device and it fits and works fine (though not sure if the yogurt container plastic leeches chemicals or not).  Anyway, this way I can make a batch and put it directly into the fridge and then make another batch right away.  I tried making a batch, with 1% milk, using just my pro-biotic pills (which have all the good bacteria you find in a good yogurt).  And it worked pretty well, but was a bit runny, as compared to using the same milk and 1/4 cup yogurt as starter. I've also found that letting the thing go 24 hours doesn't make the yogurt too tangy, for me, but I don't mind tangy yogurt.  Having said that, not sure if it really was any thicker at 24 hours than it was at 12 hours.  Now trying some soy yogurt made with soy milk.  From what I've read, you need some sugar in the milk for the bugs to eat (thus, unsweetened soy will need you to add some sugar, regular soy is sweetened already).  Also, soy apparently makes a runnier yogurt, so you need to add a thickener - some have recommended 1T of pectin per 4c or so of milk, so trying that.  Also added 1/2 c dried milk, and used some yogurt as the starter.  We'll see how it works.  I don't like all the sugar in full-strength chocolate soy milk, though you could probably make a great yogurt out of it (or chocolate milk), so I'm trying half unsweetened soy and half chocolate soy, with a T of vanilla and a T of chocolate milk powder as well. Anyway, it's all an experiment, but even the runnier stuff makes a great drink.  Oh, one more thing, I did my reading on whey, the "water" that often separates from the yogurt in the fridge (and drips off if you strain the yogurt).  The whey is way full of protein and other good stuff.  And it tastes like yogurt.  I just mixed it with some sugar and drank it - it was good, tasted like kefir, or any other yogurt drink you might buy.  Seems a shame to throw it out if you're straining yogurt. This way I don't feel so bad about straining it, since I know I'll drink the whey.  Oh, and the strainer everyone recommends works great too, and was easy to rinse, thank God :-)
