# tl;dr if state_machine is in the model when a record is created, there is a record in Mongo, but you can't do a find() on it

# If state_machine is in the model when the record is created:

ruby-1.9.2-p0 > Upload.first.id
 => BSON::ObjectId('4db2a774c4054453d000000c')

Makes 6 regular or 8 smaller, takes about an hour or 40 mins if in a hurry.

For flour you can use white, wholemeal or my favourite: 50% untreated strong white flour (from Garboldisham mill) and 50% Hovis granary.

Even when I make wholemeal I use 50% white or they come out too heavy.

    * 500g flour
    * 280ml warm water
    * 1.5 tsp yeast (like Allinson Dried Active Yeast)
    * 1 tsp sugar
