The idea of "food trends" is introduced, with references to platforms like Yummly, which serves as a social media site for food enthusiasts. Participants share their cooking habits, with some unfamiliar with certain ingredients like Himalayan pink salt and nutritional yeast, while others mention their preference for local and seasonal foods over trendy items. There is a distinction made between active and deactivated yeast, with nutritional yeast highlighted as a popular ingredient among vegans for its cheese-like flavor. Overall, the conversation reflects a mix of indifference towards mainstream trends and a focus on personal comfort and practicality in food and fashion choices.
