Answer to a 4 year old question!
Baking with ovens is more of a bonus than an early goal to shoot for and rely on. Livestock and even food from occupations/minors is a better deal than baking. Especially in 4 or 5 player games it's WAY too easy to be blocked out of huge baking action when you need it.
Pat's list has the right idea, although Pottery is by far the best of the "workshop" improvements. Clay is the most abundant resource in 90% of games. You can never have enough wood between building rooms, fences, and improvements. Reed is also scarce to the point that it's the primary bottleneck for development. Why would you eat it? Clay is almost as abundant as wood and is mostly only used for a cooking improvement and renovation; there's plenty of it and it's not too difficult to get food out of the Pottery every harvest and the full +3 bonus points.
