Hi Mum2three,
Here's my feeback:
1. How to store the grain in bulk & also in smaller quantities (i.e. 1 or 5kg & 25-30kg)
The maximum I store in is 5kg and have the largest tupperware modular mates which holds 5kg of flour. Some hospitality supply outlets sell larger containers (ie Campbells Cash & Carry etc) that would probably hold maybe up to 20kg.
2. How to mill the grain in the thermomix, as there is nothing in the recipe book
In your cookbook you should have a Summary Table for Basic Functions to sit on the fridge and it should also be printed in the front part of the book. Milling grains can take anywhere between 20seconds to 2 mins on speed 9-10.
3. Can I replace the Bakers Flour in the recipes to some sort of grain? I would prefer to use fresher ingrediants
Im not sure about this one - there are others on the forum who could answer this better as I use a combination and havent tried all freshly milled grains.
Good luck when you get started - and good luck with the move!!
