Neil Barrett runs a catering and workshop business in Dublin and as part of that he offers the following two classes:
How to make fabulous Bread: you may never buy it again. You will learn a recipe for a Master Dough and from that you can make any number of Breads. I will also go through the steps for authentic Sourdough and Quick breads too.
Basics of Fermentation: We have been selling for quite some time, various types of fermentation culture from sourdoughs (where my real interest was born) to scobies and the like.
