I've been making Granary bread for awhile now in our bread maker but I have just run out of white flower so my question is if I make a 1kg loaf:

water 350ml

vegetablie oil 1.5 tbsp

lemon juice 4 tsp

granary bread 540g

white bread flower 60g

skimmed milk 2 tbsp

salt 2 tsp

brown soft sugar 2 tsp

yeast 2 tsp

can I still make the loaf with 600g of granay flower instead of the 540g or do I need to use the 60g of white flower,???
