Several amateur and professional cooking and homemaking websites have glossaries of cooking terms on their websites, including Better Homes and Gardens, at BHG.com, and GoodHousekeeping.com. Both sites provide free glossaries with dozens of the most widely used cooking terms for a variety of cuisines.
Both sites put the glossaries on one page, in alphabetical order, for easy navigation. Better Homes and Gardens also offers full color photographs to go along with the descriptions.
The USDA recommends several resources on its website, usda.gov, including the BBC's Online Food Glossary, a baking glossary from the Home Baking Association, a glossary of cooking terms from the University of Minnesota-Duluth and links to more advanced cooking glossaries that cover topics such as herbs and spices and ingredient substitution.
Another large online cooking glossary is the culinary dictionary on Linda Stradley's popular amateur website WhatsCookingAmerica.net. It includes the definitions and history of hundreds of cooking, food and beverage terms. The site has been active since 1997, and boasts 3 million users every month, with 57 million users in 2013 alone.
For more in-depth research, Wikipedia.org also offers a category page with over 120 links to full Wikipedia pages related to culinary terms. There are also subcategory pages for more advanced terms related to topics such as cutting techniques.
