Its does say to use 300ml milk, but i used 1/2 and 1/2 milk and water. and used some of my HEA for it
Does the Asda's one taste ok? with just water??
Yes, the ASDA one tasted fine but it depends if you like packet mixes. I have tried the schwartz one before but you have to add milk to it and I like to keep my HEXa for other things. Although, I might try it next time.
I think the mix works the same way as the just add water pasta and sauces. I didn't look at the ingredients on the back but maybe it contains milk already so you don't have to add it.
