Milk is an important source of nutrients that you and your family shouldnt miss out on. If someone in your family has lactose intolerance and the rest of the family still want to enjoy the taste of real milk, try Lactofree - the UKs first virtually lactose-free dairy drink.
I have a good book called teh Ken Hom Wok - it is very good and takes you through all the steps.
I find the key thing for Chinese cooking is to prepare all your raw ingredients in advance into little dishes. The actual cooking is very fast and you don't have time to do any chopping in between.
with most chinese takeaways in the UK the secret ingredients are indeed a) msg and b) cornflour. That's what gives the viscosity and shininess to the sauces.
And as for chinese curry, it comes from a can and you can get it at Win Yip or any good chinese supermarket, don't try and do this at home
Chinese people very seldom order from a takeaway! Depends what your definition of Chinese food is. Stir fries are very quick. I find that you need a lot of space for doing a variety of dishes and you end up doing a lot of washing up as well.
Loads of preparation - all needs to be done and ready in little dishes, as cooking is quick and everything needs to be ready, and to hand. Can be nice, but to get a mix of dishes, you need a 'hostess' or similar to keep it hot, once ready, while you cook the next one. You end up with loads of washing up. Nice, but different from a takeaway.
