Its guiding idea is that understanding not only what to do in the kitchen, but why it works, can help people become better cooks. The site is associated with Mark Michalski, an avid foodie and lifelong engineer, and presents food through practical recipes and technical curiosity.

Its recipe collection spans appetizers, baked goods, beef, desserts, drinks, lamb, pasta, pork, poultry, salads, sauces, seafood, soups, spice mixes and vegetables. Featured dishes include fresh salmon cakes, Irish corned beef and cabbage, lentil and pasta soup, and a range of pestos and relishes. Alongside recipes, sizzle&STEM shares how-to guidance, food mathematics, book recommendations, information about food manufacturing and engineering, appliance science, videos and podcasts. It also highlights friends of the brand and their recipes, extending its perspective through guest contributors and conversations, including discussions about manufacturing and engineering.
