How to make sweet-tasting noodles? I've never made noodle dough before, and I want to try it today. However, I'd like to make the noodles more sweet. 

Is the base ingredient ratio for making the noodle dough one egg per 100g flour?

How can I make it sweeter? Would I just add sugar or is there a better ingredient to add that will not change the texture of the noodles? 

Will adding butter and milk change the texture of the noodle?
Butter and milk will add fat and water which will definitely change the consistency of the dough. You will have to adjust the ratios if you add them (surely more flour if you add milk).

If you want sweet noodles my best bet would be to add sugar, although I wouldn't do sweet egg noodles... maybe sweet rice noodles?

Why don't you just do plain noodles and then make a sweet condiment instead?
