What about doing the initial mix yourself and then using their ovens for a small fee. Save the cost of purchasing/installing a professional oven. In places like Greece it used to be a common thing to utilise the residual heat of the towns bakery oven by having your meals taken there to be cooked ( for a donation). Or, what if you put in an order for something like a dozen loaves of yeast-less bread using a rising agent I'm sure one of the bakers would be happy to oblige. Lots of luck. Yotmon.
Ps - I tried 50gms of flour with 100g of water, pinch of baking powder and cream of tartare in the microwave for 2.5 mins - turned into a brick, when I grated it, it reduced to a fine powder. Re-hydrated it but stayed tacky - birds in the garden seemed to like it.
As Bri-Can says, probably easier to import from Uk. Most wholesalers sell for around £25 sack - 25 kilos. (9238 Forint ) depending on exchange rate plus postage.
Try Scobies, they export as far as Cameroon so should include Hungary. http://www.scobiesdirect.com/Products.a ... 26+Oatmeal
Hope this helps. Yotmon.
