What is the underlying cooking principle that transfers knowledge from the Tefal endorsement to modern multi-cookers like the Instant Pot?

Rapid, sealed cooking

While Jamie Oliver’s primary endorsement focused on a specific set of hardware, namely stovetop or electric pressure cookers from Tefal, the fundamental concept being promoted remains applicable across various technologies. Even as home cooks transition to newer devices such as the Instant Pot, the core mechanism remains unchanged. This constant is the principle of rapid, sealed cooking under pressure. Recognizing this shared underlying process allows home cooks to effectively transfer the knowledge, techniques, and culinary understanding gained from the earlier Tefal endorsements to the operation of contemporary, widely adopted electric multi-cookers.
