Sharing cooking recipes is a great way to exchange culinary ideas and provide
instructions for food preparation. However, categorizing raw recipes found
online into appropriate food genres can be challenging due to a lack of
adequate labeled data. In this study, we present a dataset named the
``Assorted, Archetypal, and Annotated Two Million Extended (3A2M+) Cooking
Recipe Dataset" that contains two million culinary recipes labeled in
respective categories with extended named entities extracted from recipe
descriptions. This collection of data includes various features such as title,
NER, directions, and extended NER, as well as nine different labels
representing genres including bakery, drinks, non-veg, vegetables, fast food,
cereals, meals, sides, and fusions. The proposed pipeline named 3A2M+ extends
the size of the Named Entity Recognition (NER) list to address missing named
entities like heat, time or process from the recipe directions using two NER
extraction tools. 3A2M+ dataset provides a comprehensive solution to the
various challenging recipe-related tasks, including classification, named
entity recognition, and recipe generation. Furthermore, we have demonstrated
traditional machine learning, deep learning and pre-trained language models to
classify the recipes into their corresponding genre and achieved an overall
accuracy of 98.6\%. Our investigation indicates that the title feature played a
more significant role in classifying the genre.
