If you prefer a less sour version, use 1. For a more sour flavor, use 2 lemons.

Hi Peter,

from what I’ve gathered from Elaine’s recipes the amount of meat per portion tends to be roughly between 100 and 200g with anything above 150g being more the exception than the rule. Note however that she pointed out elsewhere that in Chinese cooking serving more people is done by adding more dishes instead of adding more of the same ingredient to one dish. Apart from that any dish seems to imply that it is served with rice, some soup and at least one other side dish like salad or vegetables, so you’ll have to take them into consideration, too.

To illustrate, if you make this with a soup which contains pork ribs and a side dish like lotus root salad and go for a cup of rice per person you want much less meat than when you skip the soup, have some bean sprouts as salad and only eat half a cup of rice.

That’s why I think your question cannot be answered with a precise number.

Yes,
If you use orange juice, skip lemon.
