I am not sure what type of information you are needing on traditional food. From the Library's LibGuide Welcome page (link below), select 'Databases by Subject'. The various subject areas you may be interested in are: Reference, Science, Multiple topics or maybe History and Genealogy.
One of the databases listed in Multiple Topics is: CREDO Reference. After opening CREDO Reference, click on Find a Book. One of the subject categories is Food and Beverage.
Another database you will see in many of our subject areas is EBSCO: Academic Search Complete. This source can often help to narrow down a topic.
For more help in using these resources, check the How to use EBSCO LibGuide (link below) and/or How to use CREDO Reference LibGuide (link below)
